1=1847
2=System
3=The System performance object consists of counters that apply to more than one instance of a component processors on the computer.
4=Memory
5=The Memory performance object consists of counters that describe the behavior of physical and virtual memory on the computer. Physical memory is the amount of random access memory on the computer. Virtual memory consists of the space in physical memory and on disk. Many of the memory counters monitor paging, which is the movement of pages of code and data between disk and physical memory. Excessive paging, a symptom of a memory shortage, can cause delays which interfere with all system processes.
6=% Processor Time
7=% Processor Time is the percentage of elapsed time that the processor spends to execute a non-Idle thread. It is calculated by measuring the percentage of time that the processor spends executing the idle thread and then subtracting that value from 100%. (Each processor has an idle thread that consumes cycles when no other threads are ready to run). This counter is the primary indicator of processor activity, and displays the average percentage of busy time observed during the sample interval. It should be noted that the accounting calculation of whether the processor is idle is performed at an internal sampling interval of the system clock (10ms). On todays fast processors, % Processor Time can therefore underestimate the processor utilization as the processor may be spending a lot of time servicing threads between the system clock sampling interval. Workload based timer applications are one example of applications which are more likely to be measured inaccurately as timers are signaled just after the sample is taken.
9=% Total DPC Time is the average percentage of time that all processors spend receiving and servicing deferred procedure calls (DPCs). (DPCs are interrupts that run at a lower priority than the standard interrupts). It is the sum of Processor: % DPC Time for all processors on the computer, divided by the number of processors. System: % Total DPC Time is a component of System: % Total Privileged Time because DPCs are executed in privileged mode. DPCs are counted separately and are not a component of the interrupt count. This counter displays the average busy time as a percentage of the sample time.
10=File Read Operations/sec
11=File Read Operations/sec is the combined rate of file system read requests to all devices on the computer, including requests to read from the file system cache. It is measured in numbers of reads. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
12=File Write Operations/sec
13=File Write Operations/sec is the combined rate of the file system write requests to all devices on the computer, including requests to write to data in the file system cache. It is measured in numbers of writes. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
14=File Control Operations/sec
15=File Control Operations/sec is the combined rate of file system operations that are neither reads nor writes, such as file system control requests and requests for information about device characteristics or status. This is the inverse of System: File Data Operations/sec and is measured in number of operations perf second. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
16=File Read Bytes/sec
17=File Read Bytes/sec is the overall rate at which bytes are read to satisfy file system read requests to all devices on the computer, including reads from the file system cache. It is measured in number of bytes per second. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
18=File Write Bytes/sec
19=File Write Bytes/sec is the overall rate at which bytes are written to satisfy file system write requests to all devices on the computer, including writes to the file system cache. It is measured in number of bytes per second. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
20=File Control Bytes/sec
21=File Control Bytes/sec is the overall rate at which bytes are transferred for all file system operations that are neither reads nor writes, including file system control requests and requests for information about device characteristics or status. It is measured in numbers of bytes. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
23=% Total Interrupt Time is the average percentage of time that all processors spend receiving and servicing hardware interrupts during sample intervals, where the value is an indirect indicator of the activity of devices that generate interrupts. It is the sum of Processor: % Interrupt Time for of all processors on the computer, divided by the number of processors. DPCs are counted separately and are not a component of the interrupt count. This value is an indirect indicator of the activity of devices that generate interrupts, such as the system timer, the mouse, disk drivers, data communication lines, network interface cards and other peripheral devices.
24=Available Bytes
25=Available Bytes is the amount of physical memory, in bytes, immediately available for allocation to a process or for system use. It is equal to the sum of memory assigned to the standby (cached), free and zero page lists.
26=Committed Bytes
27=Committed Bytes is the amount of committed virtual memory, in bytes. Committed memory is the physical memory which has space reserved on the disk paging file(s). There can be one or more paging files on each physical drive. This counter displays the last observed value only; it is not an average.
28=Page Faults/sec
29=Page Faults/sec is the average number of pages faulted per second. It is measured in number of pages faulted per second because only one page is faulted in each fault operation, hence this is also equal to the number of page fault operations. This counter includes both hard faults (those that require disk access) and soft faults (where the faulted page is found elsewhere in physical memory.) Most processors can handle large numbers of soft faults without significant consequence. However, hard faults, which require disk access, can cause significant delays.
30=Commit Limit
31=Commit Limit is the amount of virtual memory that can be committed without having to extend the paging file(s). It is measured in bytes. Committed memory is the physical memory which has space reserved on the disk paging files. There can be one paging file on each logical drive). If the paging file(s) are be expanded, this limit increases accordingly. This counter displays the last observed value only; it is not an average.
32=Write Copies/sec
33=Write Copies/sec is the rate at which page faults are caused by attempts to write that have been satisfied by coping of the page from elsewhere in physical memory. This is an economical way of sharing data since pages are only copied when they are written to; otherwise, the page is shared. This counter shows the number of copies, without regard for the number of pages copied in each operation.
34=Transition Faults/sec
35=Transition Faults/sec is the rate at which page faults are resolved by recovering pages that were being used by another process sharing the page, or were on the modified page list or the standby list, or were being written to disk at the time of the page fault. The pages were recovered without additional disk activity. Transition faults are counted in numbers of faults; because only one page is faulted in each operation, it is also equal to the number of pages faulted.
36=Cache Faults/sec
37=Cache Faults/sec is the rate at which faults occur when a page sought in the file system cache is not found and must be retrieved from elsewhere in memory (a soft fault) or from disk (a hard fault). The file system cache is an area of physical memory that stores recently used pages of data for applications. Cache activity is a reliable indicator of most application I/O operations. This counter shows the number of faults, without regard for the number of pages faulted in each operation.
38=Demand Zero Faults/sec
39=Demand Zero Faults/sec is the rate at which a zeroed page is required to satisfy the fault. Zeroed pages, pages emptied of previously stored data and filled with zeros, are a security feature of Windows that prevent processes from seeing data stored by earlier processes that used the memory space. Windows maintains a list of zeroed pages to accelerate this process. This counter shows the number of faults, without regard to the number of pages retrieved to satisfy the fault. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
40=Pages/sec
41=Pages/sec is the rate at which pages are read from or written to disk to resolve hard page faults. This counter is a primary indicator of the kinds of faults that cause system-wide delays. It is the sum of Memory\\Pages Input/sec and Memory\\Pages Output/sec. It is counted in numbers of pages, so it can be compared to other counts of pages, such as Memory\\Page Faults/sec, without conversion. It includes pages retrieved to satisfy faults in the file system cache (usually requested by applications) non-cached mapped memory files.
42=Page Reads/sec
43=Page Reads/sec is the rate at which the disk was read to resolve hard page faults. It shows the number of reads operations, without regard to the number of pages retrieved in each operation. Hard page faults occur when a process references a page in virtual memory that is not in working set or elsewhere in physical memory, and must be retrieved from disk. This counter is a primary indicator of the kinds of faults that cause system-wide delays. It includes read operations to satisfy faults in the file system cache (usually requested by applications) and in non-cached mapped memory files. Compare the value of Memory\\Pages Reads/sec to the value of Memory\\Pages Input/sec to determine the average number of pages read during each operation.
44=Processor Queue Length
45=Processor Queue Length is the number of threads in the processor queue. Unlike the disk counters, this counter counters, this counter shows ready threads only, not threads that are running. There is a single queue for processor time even on computers with multiple processors. Therefore, if a computer has multiple processors, you need to divide this value by the number of processors servicing the workload. A sustained processor queue of less than 10 threads per processor is normally acceptable, dependent of the workload.
46=Thread State
47=Thread State is the current state of the thread. It is 0 for Initialized, 1 for Ready, 2 for Running, 3 for Standby, 4 for Terminated, 5 for Wait, 6 for Transition, 7 for Unknown. A Running thread is using a processor; a Standby thread is about to use one. A Ready thread wants to use a processor, but is waiting for a processor because none are free. A thread in Transition is waiting for a resource in order to execute, such as waiting for its execution stack to be paged in from disk. A Waiting thread has no use for the processor because it is waiting for a peripheral operation to complete or a resource to become free.
48=Pages Output/sec
49=Pages Output/sec is the rate at which pages are written to disk to free up space in physical memory. Pages are written back to disk only if they are changed in physical memory, so they are likely to hold data, not code. A high rate of pages output might indicate a memory shortage. Windows writes more pages back to disk to free up space when physical memory is in short supply. This counter shows the number of pages, and can be compared to other counts of pages, without conversion.
50=Page Writes/sec
51=Page Writes/sec is the rate at which pages are written to disk to free up space in physical memory. Pages are written to disk only if they are changed while in physical memory, so they are likely to hold data, not code. This counter shows write operations, without regard to the number of pages written in each operation. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
52=Browser
53=The Browser performance object consists of counters that measure the rates of announcements, enumerations, and other Browser transmissions.
54=Announcements Server/sec
55=Announcements Server/sec is the rate at which the servers in this domain have announced themselves to this server.
56=Pool Paged Bytes
57=Pool Paged Bytes is the size, in bytes, of the paged pool, an area of the system virtual memory that is used for objects that can be written to disk when they are not being used. Memory\\Pool Paged Bytes is calculated differently than Process\\Pool Paged Bytes, so it might not equal Process(_Total)\\Pool Paged Bytes. This counter displays the last observed value only; it is not an average.
58=Pool Nonpaged Bytes
59=Pool Nonpaged Bytes is the size, in bytes, of the nonpaged pool, an area of the system virtual memory that is used for objects that cannot be written to disk, but must remain in physical memory as long as they are allocated. Memory\\Pool Nonpaged Bytes is calculated differently than Process\\Pool Nonpaged Bytes, so it might not equal Process(_Total)\\Pool Nonpaged Bytes. This counter displays the last observed value only; it is not an average.
60=Pool Paged Allocs
61=Pool Paged Allocs is the number of calls to allocate space in the paged pool. The paged pool is an area of the system virtual memory that is used for objects that can be written to disk when they are not being used. It is measured in numbers of calls to allocate space, regardless of the amount of space allocated in each call. This counter displays the last observed value only; it is not an average.
63=Pool Paged Resident Bytes is the size, in bytes, of the portion of the paged pool that is currently resident and active in physical memory. The paged pool is an area of the system virtual memory that is used for objects that can be written to disk when they are not being used. This counter displays the last observed value only; it is not an average.
64=Pool Nonpaged Allocs
65=Pool Nonpaged Allocs is the number of calls to allocate space in the nonpaged pool. The nonpaged pool is an area of system memory area for objects that cannot be written to disk, and must remain in physical memory as long as they are allocated. It is measured in numbers of calls to allocate space, regardless of the amount of space allocated in each call. This counter displays the last observed value only; it is not an average.
66=Pool Paged Resident Bytes
67=Bytes Total/sec is the total rate of bytes sent to or received from the network by the protocol, but only for the frames (packets) which carry data. This is the sum of Frame Bytes/sec and Datagram Bytes/sec.
68=System Code Total Bytes
69=System Code Total Bytes is the size, in bytes, of the pageable operating system code currently mapped into the system virtual address space. This value is calculated by summing the bytes in Ntoskrnl.exe, Hal.dll, the boot drivers, and file systems loaded by Ntldr/osloader. This counter does not include code that must remain in physical memory and cannot be written to disk. This counter displays the last observed value only; it is not an average.
70=System Code Resident Bytes
71=System Code Resident Bytes is the size, in bytes, of the pageable operating system code that is currently resident and active in physical memory. This value is a component of Memory\\System Code Total Bytes. Memory\\System Code Resident Bytes (and Memory\\System Code Total Bytes) does not include code that must remain in physical memory and cannot be written to disk. This counter displays the last observed value only; it is not an average.
72=System Driver Total Bytes
73=System Driver Total Bytes is the size, in bytes, of the pageable virtual memory currently being used by device drivers. Pageable memory can be written to disk when it is not being used. It includes both physical memory (Memory\\System Driver Resident Bytes) and code and data paged to disk. It is a component of Memory\\System Code Total Bytes. This counter displays the last observed value only; it is not an average.
74=System Driver Resident Bytes
75=System Driver Resident Bytes is the size, in bytes, of the pageable physical memory being used by device drivers. It is the working set (physical memory area) of the drivers. This value is a component of Memory\\System Driver Total Bytes, which also includes driver memory that has been written to disk. Neither Memory\\System Driver Resident Bytes nor Memory\\System Driver Total Bytes includes memory that cannot be written to disk.
76=System Cache Resident Bytes
77=System Cache Resident Bytes is the size, in bytes, of the portion of the system file cache which is currently resident and active in physical memory. The System Cache Resident Bytes and Memory\\Cache Bytes counters are equivalent. This counter displays the last observed value only; it is not an average.
78=Announcements Domain/sec
79=Announcements Domain/sec is the rate at which a domain has announced itself to the network.
80=Election Packets/sec
81=Election Packets/sec is the rate at which browser election packets have been received by this workstation.
82=Mailslot Writes/sec
83=Mailslot Writes/sec is the rate at which mailslot messages have been successfully received.
84=Server List Requests/sec
85=Server List Requests/sec is the rate at which requests to retrieve a list of browser servers have been processed by this workstation.
86=Cache
87=The Cache performance object consists of counters that monitor the file system cache, an area of physical memory that stores recently used data as long as possible to permit access to the data without having to read from the disk. Because applications typically use the cache, the cache is monitored as an indicator of application I/O operations. When memory is plentiful, the cache can grow, but when memory is scarce, the cache can become too small to be effective.
88=Data Maps/sec
89=Data Maps/sec is the frequency that a file system such as NTFS, maps a page of a file into the file system cache to read the page.
90=Sync Data Maps/sec
91=Sync Data Maps/sec counts the frequency that a file system, such as NTFS, maps a page of a file into the file system cache to read the page, and wishes to wait for the page to be retrieved if it is not in main memory.
92=Async Data Maps/sec
93=Async Data Maps/sec is the frequency that an application using a file system, such as NTFS, to map a page of a file into the file system cache to read the page, and does not wait for the page to be retrieved if it is not in main memory.
94=Data Map Hits %
95=Data Map Hits is the percentage of data maps in the file system cache that could be resolved without having to retrieve a page from the disk, because the page was already in physical memory.
96=Data Map Pins/sec
97=Data Map Pins/sec is the frequency of data maps in the file system cache that resulted in pinning a page in main memory, an action usually preparatory to writing to the file on disk. While pinned, a page's physical address in main memory and virtual address in the file system cache will not be altered.
98=Pin Reads/sec
99=Pin Reads/sec is the frequency of reading data into the file system cache preparatory to writing the data back to disk. Pages read in this fashion are pinned in memory at the completion of the read. While pinned, a page's physical address in the file system cache will not be altered.
100=Sync Pin Reads/sec
101=Sync Pin Reads/sec is the frequency of reading data into the file system cache preparatory to writing the data back to disk. Pages read in this fashion are pinned in memory at the completion of the read. The file system will not regain control until the page is pinned in the file system cache, in particular if the disk must be accessed to retrieve the page. While pinned, a page's physical address in the file system cache will not be altered.
102=Async Pin Reads/sec
103=Async Pin Reads/sec is the frequency of reading data into the file system cache preparatory to writing the data back to disk. Pages read in this fashion are pinned in memory at the completion of the read. The file system will regain control immediately even if the disk must be accessed to retrieve the page. While pinned, a page's physical address will not be altered.
104=Pin Read Hits %
105=Pin Read Hits is the percentage of pin read requests that hit the file system cache, i.e., did not require a disk read in order to provide access to the page in the file system cache. While pinned, a page's physical address in the file system cache will not be altered. The LAN Redirector uses this method for retrieving data from the cache, as does the LAN Server for small transfers. This is usually the method used by the disk file systems as well.
106=Copy Reads/sec
107=Copy Reads/sec is the frequency of reads from pages of the file system cache that involve a memory copy of the data from the cache to the application's buffer. The LAN Redirector uses this method for retrieving information from the file system cache, as does the LAN Server for small transfers. This is a method used by the disk file systems as well.
108=Sync Copy Reads/sec
109=Sync Copy Reads/sec is the frequency of reads from pages of the file system cache that involve a memory copy of the data from the cache to the application's buffer. The file system will not regain control until the copy operation is complete, even if the disk must be accessed to retrieve the page.
110=Async Copy Reads/sec
111=Async Copy Reads/sec is the frequency of reads from pages of the file system cache that involve a memory copy of the data from the cache to the application's buffer. The application will regain control immediately even if the disk must be accessed to retrieve the page.
112=Copy Read Hits %
113=Copy Read Hits is the percentage of cache copy read requests that hit the cache, that is, they did not require a disk read in order to provide access to the page in the cache. A copy read is a file read operation that is satisfied by a memory copy from a page in the cache to the application's buffer. The LAN Redirector uses this method for retrieving information from the cache, as does the LAN Server for small transfers. This is a method used by the disk file systems as well.
114=MDL Reads/sec
115=MDL Reads/sec is the frequency of reads from the file system cache that use a Memory Descriptor List (MDL) to access the data. The MDL contains the physical address of each page involved in the transfer, and thus can employ a hardware Direct Memory Access (DMA) device to effect the copy. The LAN Server uses this method for large transfers out of the server.
116=Sync MDL Reads/sec
117=Sync MDL Reads/sec is the frequency of reads from the file system cache that use a Memory Descriptor List (MDL) to access the pages. The MDL contains the physical address of each page in the transfer, thus permitting Direct Memory Access (DMA) of the pages. If the accessed page(s) are not in main memory, the caller will wait for the pages to fault in from the disk.
118=Async MDL Reads/sec
119=Async MDL Reads/sec is the frequency of reads from the file system cache that use a Memory Descriptor List (MDL) to access the pages. The MDL contains the physical address of each page in the transfer, thus permitting Direct Memory Access (DMA) of the pages. If the accessed page(s) are not in main memory, the calling application program will not wait for the pages to fault in from disk.
120=MDL Read Hits %
121=MDL Read Hits is the percentage of Memory Descriptor List (MDL) Read requests to the file system cache that hit the cache, i.e., did not require disk accesses in order to provide memory access to the page(s) in the cache.
122=Read Aheads/sec
123=Read Aheads/sec is the frequency of reads from the file system cache in which the Cache detects sequential access to a file. The read aheads permit the data to be transferred in larger blocks than those being requested by the application, reducing the overhead per access.
124=Fast Reads/sec
125=Fast Reads/sec is the frequency of reads from the file system cache that bypass the installed file system and retrieve the data directly from the cache. Normally, file I/O requests invoke the appropriate file system to retrieve data from a file, but this path permits direct retrieval of data from the cache without file system involvement if the data is in the cache. Even if the data is not in the cache, one invocation of the file system is avoided.
126=Sync Fast Reads/sec
127=Sync Fast Reads/sec is the frequency of reads from the file system cache that bypass the installed file system and retrieve the data directly from the cache. Normally, file I/O requests invoke the appropriate file system to retrieve data from a file, but this path permits direct retrieval of data from the cache without file system involvement if the data is in the cache. Even if the data is not in the cache, one invocation of the file system is avoided. If the data is not in the cache, the request (application program call) will wait until the data has been retrieved from disk.
128=Async Fast Reads/sec
129=Async Fast Reads/sec is the frequency of reads from the file system cache that bypass the installed file system and retrieve the data directly from the cache. Normally, file I/O requests will invoke the appropriate file system to retrieve data from a file, but this path permits data to be retrieved from the cache directly (without file system involvement) if the data is in the cache. Even if the data is not in the cache, one invocation of the file system is avoided. If the data is not in the cache, the request (application program call) will not wait until the data has been retrieved from disk, but will get control immediately.
130=Fast Read Resource Misses/sec
131=Fast Read Resource Misses/sec is the frequency of cache misses necessitated by the lack of available resources to satisfy the request.
132=Fast Read Not Possibles/sec
133=Fast Read Not Possibles/sec is the frequency of attempts by an Application Program Interface (API) function call to bypass the file system to get to data in the file system cache that could not be honored without invoking the file system.
134=Lazy Write Flushes/sec
135=Lazy Write Flushes/sec is the rate at which the Lazy Writer thread has written to disk. Lazy Writing is the process of updating the disk after the page has been changed in memory, so that the application that changed the file does not have to wait for the disk write to be complete before proceeding. More than one page can be transferred by each write operation.
136=Lazy Write Pages/sec
137=Lazy Write Pages/sec is the rate at which the Lazy Writer thread has written to disk. Lazy Writing is the process of updating the disk after the page has been changed in memory, so that the application that changed the file does not have to wait for the disk write to be complete before proceeding. More than one page can be transferred on a single disk write operation.
138=Data Flushes/sec
139=Data Flushes/sec is the rate at which the file system cache has flushed its contents to disk as the result of a request to flush or to satisfy a write-through file write request. More than one page can be transferred on each flush operation.
140=Data Flush Pages/sec
141=Data Flush Pages/sec is the number of pages the file system cache has flushed to disk as a result of a request to flush or to satisfy a write-through file write request. More than one page can be transferred on each flush operation.
142=% User Time
143=% User Time is the percentage of elapsed time the processor spends in the user mode. User mode is a restricted processing mode designed for applications, environment subsystems, and integral subsystems. The alternative, privileged mode, is designed for operating system components and allows direct access to hardware and all memory. The operating system switches application threads to privileged mode to access operating system services. This counter displays the average busy time as a percentage of the sample time.
144=% Privileged Time
145=% Privileged Time is the percentage of elapsed time that the process threads spent executing code in privileged mode. When a Windows system service in called, the service will often run in privileged mode to gain access to system-private data. Such data is protected from access by threads executing in user mode. Calls to the system can be explicit or implicit, such as page faults or interrupts. Unlike some early operating systems, Windows uses process boundaries for subsystem protection in addition to the traditional protection of user and privileged modes. Some work done by Windows on behalf of the application might appear in other subsystem processes in addition to the privileged time in the process.
146=Context Switches/sec
147=Context Switches/sec is the combined rate at which all processors on the computer are switched from one thread to another. Context switches occur when a running thread voluntarily relinquishes the processor, is preempted by a higher priority ready thread, or switches between user-mode and privileged (kernel) mode to use an Executive or subsystem service. It is the sum of Thread\\Context Switches/sec for all threads running on all processors in the computer and is measured in numbers of switches. There are context switch counters on the System and Thread objects. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
148=Interrupts/sec
149=Interrupts/sec is the average rate, in incidents per second, at which the processor received and serviced hardware interrupts. It does not include deferred procedure calls (DPCs), which are counted separately. This value is an indirect indicator of the activity of devices that generate interrupts, such as the system clock, the mouse, disk drivers, data communication lines, network interface cards, and other peripheral devices. These devices normally interrupt the processor when they have completed a task or require attention. Normal thread execution is suspended. The system clock typically interrupts the processor every 10 milliseconds, creating a background of interrupt activity. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
150=System Calls/sec
151=System Calls/sec is the combined rate of calls to operating system service routines by all processes running on the computer. These routines perform all of the basic scheduling and synchronization of activities on the computer, and provide access to non-graphic devices, memory management, and name space management. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
152=Level 1 TLB Fills/sec
153=Level 1 TLB Fills/sec is the frequency of faults that occur when reference is made to memory whose Page Table Entry (PTE) is not in the Translation Lookaside Buffer (TLB). On some computers this fault is handled by software loading the PTE into the TLB, and this counter is incremented.
154=Level 2 TLB Fills/sec
155=Level 2 TLB Fills/sec is the frequency of faults that occur when reference is made to memory whose Page Table Entry (PTE) is not in the Translation Lookaside Buffer (TLB), nor is the page containing the PTE. On some computers this fault is handled by software loading the PTE into the TLB, and this counter is incremented.
156=Enumerations Server/sec
157=% User Time is the percentage of elapsed time that the process threads spent executing code in user mode. Applications, environment subsystems, and integral subsystems execute in user mode. Code executing in user mode cannot damage the integrity of the Windows executive, kernel, and device drivers. Unlike some early operating systems, Windows uses process boundaries for subsystem protection in addition to the traditional protection of user and privileged modes. Some work done by Windows on behalf of the application might appear in other subsystem processes in addition to the privileged time in the process.
158=Enumerations Domain/sec
159=% Privileged Time is the percentage of elapsed time that the process threads spent executing code in privileged mode. When a Windows system service is called, the service will often run in privileged mode to gain access to system-private data. Such data is protected from access by threads executing in user mode. Calls to the system can be explicit or implicit, such as page faults or interrupts. Unlike some early operating systems, Windows uses process boundaries for subsystem protection in addition to the traditional protection of user and privileged modes. Some work done by Windows on behalf of the application might appear in other subsystem processes in addition to the privileged time in the process.

172=Virtual Bytes Peak
173=Virtual Bytes Peak is the maximum size, in bytes, of virtual address space the process has used at any one time. Use of virtual address space does not necessarily imply corresponding use of either disk or main memory pages. However, virtual space is finite, and the process might limit its ability to load libraries.
174=Virtual Bytes
175=Virtual Bytes is the current size, in bytes, of the virtual address space the process is using. Use of virtual address space does not necessarily imply corresponding use of either disk or main memory pages. Virtual space is finite, and the process can limit its ability to load libraries.
177=Page Faults/sec is the rate at which page faults by the threads executing in this process are occurring. A page fault occurs when a thread refers to a virtual memory page that is not in its working set in main memory. This may not cause the page to be fetched from disk if it is on the standby list and hence already in main memory, or if it is in use by another process with whom the page is shared.
178=Working Set Peak
179=Working Set Peak is the maximum size, in bytes, of the Working Set of this process at any point in time. The Working Set is the set of memory pages touched recently by the threads in the process. If free memory in the computer is above a threshold, pages are left in the Working Set of a process even if they are not in use. When free memory falls below a threshold, pages are trimmed from Working Sets. If they are needed they will then be soft-faulted back into the Working Set before they leave main memory.
180=Working Set
181=Working Set is the current size, in bytes, of the Working Set of this process. The Working Set is the set of memory pages touched recently by the threads in the process. If free memory in the computer is above a threshold, pages are left in the Working Set of a process even if they are not in use. When free memory falls below a threshold, pages are trimmed from Working Sets. If they are needed they will then be soft-faulted back into the Working Set before leaving main memory.
182=Page File Bytes Peak
183=Page File Bytes Peak is the maximum amount of virtual memory, in bytes, that this process has reserved for use in the paging file(s). Paging files are used to store pages of memory used by the process that are not contained in other files. Paging files are shared by all processes, and the lack of space in paging files can prevent other processes from allocating memory. If there is no paging file, this counter reflects the maximum amount of virtual memory that the process has reserved for use in physical memory.
184=Page File Bytes
185=Page File Bytes is the current amount of virtual memory, in bytes, that this process has reserved for use in the paging file(s). Paging files are used to store pages of memory used by the process that are not contained in other files. Paging files are shared by all processes, and the lack of space in paging files can prevent other processes from allocating memory. If there is no paging file, this counter reflects the current amount of virtual memory that the process has reserved for use in physical memory.
186=Private Bytes
187=Private Bytes is the current size, in bytes, of memory that this process has allocated that cannot be shared with other processes.
188=Announcements Total/sec
189=% Processor Time is the percentage of elapsed time that all of process threads used the processor to execution instructions. An instruction is the basic unit of execution in a computer, a thread is the object that executes instructions, and a process is the object created when a program is run. Code executed to handle some hardware interrupts and trap conditions are included in this count.
190=Enumerations Total/sec
191=% Processor Time is the percentage of elapsed time that all of process threads used the processor to execution instructions. An instruction is the basic unit of execution in a computer, a thread is the object that executes instructions, and a process is the object created when a program is run. Code executed to handle some hardware interrupts and trap conditions are included in this count.
193=% User Time is the percentage of elapsed time that this thread has spent executing code in user mode. Applications, environment subsystems, and integral subsystems execute in user mode. Code executing in user mode cannot damage the integrity of the Windows NT Executive, Kernel, and device drivers. Unlike some early operating systems, Windows NT uses process boundaries for subsystem protection in addition to the traditional protection of user and privileged modes. These subsystem processes provide additional protection. Therefore, some work done by Windows NT on behalf of your application might appear in other subsystem processes in addition to the privileged time in your process.
195=% Privileged Time is the percentage of elapsed time that the process threads spent executing code in privileged mode. When a Windows system service in called, the service will often run in privileged mode to gain access to system-private data. Such data is protected from access by threads executing in user mode. Calls to the system can be explicit or implicit, such as page faults or interrupts. Unlike some early operating systems, Windows uses process boundaries for subsystem protection in addition to the traditional protection of user and privileged modes. Some work done by Windows on behalf of the application might appear in other subsystem processes in addition to the privileged time in the process.
197=Context Switches/sec is the rate of switches from one thread to another. Thread switches can occur either inside of a single process or across processes. A thread switch can be caused either by one thread asking another for information, or by a thread being preempted by another, higher priority thread becoming ready to run. Unlike some early operating systems, Windows NT uses process boundaries for subsystem protection in addition to the traditional protection of user and privileged modes. These subsystem processes provide additional protection. Therefore, some work done by Windows NT on behalf of an application appear in other subsystem processes in addition to the privileged time in the application. Switching to the subsystem process causes one Context Switch in the application thread. Switching back causes another Context Switch in the subsystem thread.
198=Current Disk Queue Length
199=Current Disk Queue Length is the number of requests outstanding on the disk at the time the performance data is collected. It also includes requests in service at the time of the collection. This is a instantaneous snapshot, not an average over the time interval. Multi-spindle disk devices can have multiple requests that are active at one time, but other concurrent requests are awaiting service. This counter might reflect a transitory high or low queue length, but if there is a sustained load on the disk drive, it is likely that this will be consistently high. Requests experience delays proportional to the length of this queue minus the number of spindles on the disks. For good performance, this difference should average less than two.
200=% Disk Time
201=% Disk Time is the percentage of elapsed time that the selected disk drive was busy servicing read or write requests.

232=Thread
233=The Thread performance object consists of counters that measure aspects of thread behavior. A thread is the basic object that executes instructions on a processor. All running processes have at least one thread.
234=PhysicalDisk
235=The Physical Disk performance object consists of counters that monitor hard or fixed disk drive on a computer. Disks are used to store file, program, and paging data and are read to retrieve these items, and written to record changes to them. The values of physical disk counters are sums of the values of the logical disks (or partitions) into which they are divided.
236=LogicalDisk
237=The Logical Disk performance object consists of counters that monitor logical partitions of a hard or fixed disk drives. Performance Monitor identifies logical disks by their a drive letter, such as C.
238=Processor
239=The Processor performance object consists of counters that measure aspects of processor activity. The processor is the part of the computer that performs arithmetic and logical computations, initiates operations on peripherals, and runs the threads of processes. A computer can have multiple processors. The processor object represents each processor as an instance of the object.
240=% Total Processor Time
241=% Total Processor Time is the average percentage of time that all processors on the computer are executing non-idle threads. This counter was designed as the primary indicator of processor activity on multiprocessor computers. It is equal to the sum of Process: % Processor Time for all processors, divided by the number of processors. It is calculated by summing the time that all processors spend executing the thread of the Idle process in each sample interval, subtracting that value from 100%, and dividing the difference by the number of processors on the computer. (Each processor has an Idle thread which consumes cycles when no other threads are ready to run). For example, on a multiprocessor computer, a value of 50% means that all processors are busy for half of the sample interval, or that half of the processors are busy for all of the sample interval. This counter displays the average percentage of busy time observed during the sample interval. It is calculated by monitoring the time the service was inactive, and then subtracting that value from 100%.
242=% Total User Time
243=% Total User Time is the average percentage of non-idle time all processors spend in user mode. It is the sum of Processor: % User Time for all processors on the computer, divided by the number of processors. System: % Total User Time and System: % Total Privileged Time sum to % Total Processor Time, but not always to 100%. (User mode is a restricted processing mode designed for applications, environment subsystems, and integral subsystems. The alternative, privileged mode, is designed for operating system components and allows direct access to hardware and all memory. The operating system switches application threads to privileged mode to access operating system services). This counter displays the average busy time as a percentage of the sample time.
244=% Total Privileged Time
245=% Total Privileged Time is the average percentage of non-idle time all processors spend in privileged (kernel) mode. It is the sum of Processor: % Privileged Time for all processors on the computer, divided by the number of processors. System: % Total User Time and System: % Total Privileged Time sum to % Total Processor Time, but not always to 100%. (Privileged mode is an processing mode designed for operating system components which allows direct access to hardware and all memory. The operating system switches application threads to privileged mode to access operating system services. The alternative, user mode, is a restricted processing mode designed for applications and environment subsystems). This counter displays the average busy time as a percentage of the sample time.
246=Total Interrupts/sec
247=Total Interrupts/sec is the combined rate of hardware interrupts received and serviced by all processors on the computer It is the sum of Processor: Interrupts/sec for all processors, and divided by the number of processors, and is measured in numbers of interrupts. It does not include DPCs, which are counted separately. This value is an indirect indicator of the activity of devices that generate interrupts, such as the system timer, the mouse, disk drivers, data communication lines, network interface cards and other peripheral devices. These devices normally interrupt the processor when they have completed a task or require attention. Normal thread execution is suspended during interrupts. Most system clocks interrupt the processor every 10 milliseconds, creating a background of interrupt activity. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval.
248=Processes

250=Threads
251=Threads is the number of threads in the computer at the time of data collection. This is an instantaneous count, not an average over the time interval. A thread is the basic executable entity that can execute instructions in a processor.
252=Events
253=Events is the number of events in the computer at the time of data collection. This is an instantaneous count, not an average over the time interval. An event is used when two or more threads try to synchronize execution.
254=Semaphores
255=Semaphores is the number of semaphores in the computer at the time of data collection. This is an instantaneous count, not an average over the time interval. Threads use semaphores to obtain exclusive access to data structures that they share with other threads.
256=Mutexes
257=Mutexes counts the number of mutexes in the computer at the time of data collection. This is an instantaneous count, not an average over the time interval. Mutexes are used by threads to assure only one thread is executing a particular section of code.
258=Sections
259=Sections is the number of sections in the computer at the time of data collection. This is an instantaneous count, not an average over the time interval. A section is a portion of virtual memory created by a process for storing data. A process can share sections with other processes.
260=Objects
261=The Object performance object consists of counters that monitor logical objects in the system, such as processes, threads, mutexes, and semaphores. This information can be used to detect the unnecessary consumption of computer resources. Each object requires memory to store basic information about the object.
262=Redirector
263=The Redirector performance object consists of counter that monitor network connections originating at the local computer.
264=Bytes Received/sec
265=Bytes Received/sec is the rate of bytes coming in to the Redirector from the network. It includes all application data as well as network protocol information (such as packet headers).
266=Packets Received/sec
267=Packets Received/sec is the rate at which the Redirector is receiving packets (also called SMBs or Server Message Blocks). Network transmissions are divided into packets. The average number of bytes received in a packet can be obtained by dividing Bytes Received/sec by this counter. Some packets received might not contain incoming data (for example an acknowledgment to a write made by the Redirector would count as an incoming packet).
268=Read Bytes Paging/sec
269=Read Bytes Paging/sec is the rate at which the Redirector is attempting to read bytes in response to page faults. Page faults are caused by loading of modules (such as programs and libraries), by a miss in the Cache (see Read Bytes Cache/sec), or by files directly mapped into the address space of applications (a high-performance feature of Windows NT).
270=Read Bytes Non-Paging/sec
271=Read Bytes Non-Paging/sec are those bytes read by the Redirector in response to normal file requests by an application when they are redirected to come from another computer. In addition to file requests, this counter includes other methods of reading across the network such as Named Pipes and Transactions. This counter does not count network protocol information, just application data.
272=Read Bytes Cache/sec
273=Read Bytes Cache/sec is the rate at which applications are accessing the file system cache by using the Redirector. Some of these data requests are satisfied by retrieving the data from the cache. Requests that miss the Cache cause a page fault (see Read Bytes Paging/sec).
274=Read Bytes Network/sec
275=Read Bytes Network/sec is the rate at which applications are reading data across the network. This occurs when data sought in the file system cache is not found there and must be retrieved from the network. Dividing this value by Bytes Received/sec indicates the proportion of application data traveling across the network. (see Bytes Received/sec).
276=Bytes Transmitted/sec
277=Bytes Transmitted/sec is the rate at which bytes are leaving the Redirector to the network. It includes all application data as well as network protocol information (such as packet headers and the like).
278=Packets Transmitted/sec
279=Packets Transmitted/sec is the rate at which the Redirector is sending packets (also called SMBs or Server Message Blocks). Network transmissions are divided into packets. The average number of bytes transmitted in a packet can be obtained by dividing Bytes Transmitted/sec by this counter.
280=Write Bytes Paging/sec
281=Write Bytes Paging/sec is the rate at which the Redirector is attempting to write bytes changed in the pages being used by applications. The program data changed by modules (such as programs and libraries) that were loaded over the network are 'paged out' when no longer needed. Other output pages come from the file system cache (see Write Bytes Cache/sec).
282=Write Bytes Non-Paging/sec
283=Write Bytes Non-Paging/sec is the rate at which bytes are written by the Redirector in response to normal file outputs by an application when they are redirected to another computer. In addition to file requests, this count includes other methods of writing across the network, such as Named Pipes and Transactions. This counter does not count network protocol information, just application data.
284=Write Bytes Cache/sec
285=Write Bytes Cache/sec is the rate at which applications on your computer are writing to the file system cache by using the Redirector. The data might not leave your computer immediately; it can be retained in the cache for further modification before being written to the network. This saves network traffic. Each write of a byte into the cache is counted here.
286=Write Bytes Network/sec
287=Write Bytes Network/sec is the rate at which applications are writing data across the network. This occurs when the file system cache is bypassed, such as for Named Pipes or Transactions, or when the cache writes the bytes to disk to make room for other data. Dividing this counter by Bytes Transmitted/sec will indicate the proportion of application data being to the network (see Transmitted Bytes/sec).
288=Read Operations/sec
289=File Read Operations/sec is the rate at which applications are asking the Redirector for data. Each call to a file system or similar Application Program Interface (API) call counts as one operation.
290=Read Operations Random/sec
291=Read Operations Random/sec counts the rate at which, on a file-by-file basis, reads are made that are not sequential. If a read is made using a particular file handle, and then is followed by another read that is not immediately the contiguous next byte, this counter is incremented by one.
292=Read Packets/sec
293=Read Packets/sec is the rate at which read packets are being placed on the network. Each time a single packet is sent with a request to read data remotely, this counter is incremented by one.
294=Reads Large/sec
295=Reads Large/sec is the rate at which reads over 2 times the server's negotiated buffer size are made by applications. Too many of these could place a strain on server resources. This counter is incremented once for each read. It does not count packets.
296=Read Packets Small/sec
297=Read Packets Small/sec is the rate at which reads less than one-fourth of the server's negotiated buffer size are made by applications. Too many of these could indicate a waste of buffers on the server. This counter is incremented once for each read. It does not count packets.
298=Write Operations/sec
299=File Write Operations/sec is the rate at which applications are sending data to the Redirector. Each call to a file system or similar Application Program Interface (API) call counts as one operation.
300=Write Operations Random/sec
301=Write Operations Random/sec is the rate at which, on a file-by-file basis, writes are made that are not sequential. If a write is made using a particular file handle, and then is followed by another write that is not immediately the next contiguous byte, this counter is incremented by one.
302=Write Packets/sec
303=Write Packets/sec is the rate at which writes are being sent to the network. Each time a single packet is sent with a request to write remote data, this counter is incremented by one.
304=Writes Large/sec
305=Writes Large/sec is the rate at which writes are made by applications that are over 2 times the server's negotiated buffer size. Too many of these could place a strain on server resources. This counter is incremented once for each write: it counts writes, not packets.
306=Write Packets Small/sec
307=Write Packets Small/sec is the rate at which writes are made by applications that are less than one-fourth of the server's negotiated buffer size. Too many of these could indicate a waste of buffers on the server. This counter is incremented once for each write: it counts writes, not packets.
308=Reads Denied/sec
309=Reads Denied/sec is the rate at which the server is unable to accommodate requests for Raw Reads. When a read is much larger than the server's negotiated buffer size, the Redirector requests a Raw Read which, if granted, would permit the transfer of the data without lots of protocol overhead on each packet. To accomplish this the server must lock out other requests, so the request is denied if the server is really busy.
310=Writes Denied/sec
311=Writes Denied/sec is the rate at which the server is unable to accommodate requests for Raw Writes. When a write is much larger than the server's negotiated buffer size, the Redirector requests a Raw Write which, if granted, would permit the transfer of the data without lots of protocol overhead on each packet. To accomplish this the server must lock out other requests, so the request is denied if the server is really busy.
312=Network Errors/sec
313=Network Errors/sec is the rate at which serious unexpected errors are occurring. Such errors generally indicate that the Redirector and one or more Servers are having serious communication difficulties. For example an SMB (Server Manager Block) protocol error is a Network Error. An entry is written to the System Event Log and provide details.
314=Server Sessions
315=Server Sessions counts the total number of security objects the Redirector has managed. For example, a logon to a server followed by a network access to the same server will establish one connection, but two sessions.
316=Server Reconnects
317=Server Reconnects counts the number of times your Redirector has had to reconnect to a server in order to complete a new active request. You can be disconnected by the Server if you remain inactive for too long. Locally even if all your remote files are closed, the Redirector will keep your connections intact for (nominally) ten minutes. Such inactive connections are called Dormant Connections. Reconnecting is expensive in time.
318=Connects Core
319=Connects Core counts the number of connections you have to servers running the original MS-Net SMB protocol, including MS-Net itself and Xenix and VAX's.

322=Connects Lan Manager 2.1
323=Connects LAN Manager 2.1 counts connections to LAN Manager 2.1 servers, including LMX servers.
324=Connects Windows NT
325=Connects Windows NT counts the connections to Windows 2000 or earlier computers.
326=Server Disconnects
327=Server Disconnects counts the number of times a Server has disconnected your Redirector. See also Server Reconnects.

335=The number of bytes the server has sent on the network. Indicates how busy the server is.
336=Thread Wait Reason
337=Thread Wait Reason is only applicable when the thread is in the Wait state (see Thread State). It is 0 or 7 when the thread is waiting for the Executive, 1 or 8 for a Free Page, 2 or 9 for a Page In, 3 or 10 for a Pool Allocation, 4 or 11 for an Execution Delay, 5 or 12 for a Suspended condition, 6 or 13 for a User Request, 14 for an Event Pair High, 15 for an Event Pair Low, 16 for an LPC Receive, 17 for an LPC Reply, 18 for Virtual Memory, 19 for a Page Out; 20 and higher are not assigned at the time of this writing. Event Pairs are used to communicate with protected subsystems (see Context Switches).
339=% DPC Time is the percentage of time that the processor spent receiving and servicing deferred procedure calls (DPCs) during the sample interval. DPCs are interrupts that run at a lower priority than standard interrupts. % DPC Time is a component of % Privileged Time because DPCs are executed in privileged mode. They are counted separately and are not a component of the interrupt counters. This counter displays the average busy time as a percentage of the sample time.
340=Sessions Timed Out
341=The number of sessions that have been closed due to their idle time exceeding the AutoDisconnect parameter for the server. Shows whether the AutoDisconnect setting is helping to conserve resources.
342=Sessions Errored Out
343=The number of sessions that have been closed due to unexpected error conditions or sessions that have reached the autodisconnect timeout and have been disconnected normally. The autodisconnect timeout value represents the number of seconds that idle connections with no session attached to have before being disconnected automatically by a server. The default value is 30 seconds. This counter increments as a result of normal server operation, not as an indication of network problems or unexpected error condition.
344=Sessions Logged Off

5970=.NET CLR Memory
5971=Counters for CLR Garbage Collected heap.
5972=# Gen 0 Collections
5973=This counter displays the number of times the generation 0 objects (youngest; most recently allocated) are garbage collected (Gen 0 GC) since the start of the application. Gen 0 GC occurs when the available memory in generation 0 is not sufficient to satisfy an allocation request. This counter is incremented at the end of a Gen 0 GC. Higher generation GCs include all lower generation GCs. This counter is explicitly incremented when a higher generation (Gen 1 or Gen 2) GC occurs. _Global_ counter value is not accurate and should be ignored. This counter displays the last observed value.
5974=# Gen 1 Collections
5975=This counter displays the number of times the generation 1 objects are garbage collected since the start of the application. The counter is incremented at the end of a Gen 1 GC. Higher generation GCs include all lower generation GCs. This counter is explicitly incremented when a higher generation (Gen 2) GC occurs. _Global_ counter value is not accurate and should be ignored. This counter displays the last observed value.
5976=# Gen 2 Collections
5977=This counter displays the number of times the generation 2 objects (older) are garbage collected since the start of the application. The counter is incremented at the end of a Gen 2 GC (also called full GC). _Global_ counter value is not accurate and should be ignored. This counter displays the last observed value.
5978=Promoted Memory from Gen 0
5979=This counter displays the bytes of memory that survive garbage collection (GC) and are promoted from generation 0 to generation 1; objects that are promoted just because they are waiting to be finalized are not included in this counter. This counter displays the value observed at the end of the last GC; its not a cumulative counter.
5980=Promoted Memory from Gen 1
5981=This counter displays the bytes of memory that survive garbage collection (GC) and are promoted from generation 1 to generation 2; objects that are promoted just because they are waiting to be finalized are not included in this counter. This counter displays the value observed at the end of the last GC; its not a cumulative counter. This counter is reset to 0 if the last GC was a Gen 0 GC only.
5982=Gen 0 Promoted Bytes/Sec
5983=This counter displays the bytes per second that are promoted from generation 0 (youngest) to generation 1; objects that are promoted just because they are waiting to be finalized are not included in this counter. Memory is promoted when it survives a garbage collection. This counter was designed as an indicator of relatively long-lived objects being created per sec. This counter displays the difference between the values observed in the last two samples divided by the duration of the sample interval.
5984=Gen 1 Promoted Bytes/Sec
5985=This counter displays the bytes per second that are promoted from generation 1 to generation 2 (oldest); objects that are promoted just because they are waiting to be finalized are not included in this counter. Memory is promoted when it survives a garbage collection. Nothing is promoted from generation 2 since it is the oldest. This counter was designed as an indicator of very long-lived objects being created per sec. This counter displays the difference between the values observed in the last two samples divided by the duration of the sample interval.
5986=Promoted Finalization-Memory from Gen 0
5987=This counter displays the bytes of memory that are promoted from generation 0 to generation 1 just because they are waiting to be finalized. This counter displays the value observed at the end of the last GC; its not a cumulative counter.
5988=Process ID
5989=This counter displays the process ID of the CLR process instance being monitored. The value displayed will be 0 until after the first garbage collection.
5990=Gen 0 heap size
5991=This counter displays the maximum bytes that can be allocated in generation 0 (Gen 0); its does not indicate the current number of bytes allocated in Gen 0. A Gen 0 GC is triggered when the allocations since the last GC exceed this size. The Gen 0 size is tuned by the Garbage Collector and can change during the execution of the application. At the end of a Gen 0 collection the size of the Gen 0 heap is infact 0 bytes; this counter displays the size (in bytes) of allocations that would trigger the next Gen 0 GC. This counter is updated at the end of a GC; its not updated on every allocation.
5992=Gen 1 heap size
5993=This counter displays the current number of bytes in generation 1 (Gen 1); this counter does not display the maximum size of Gen 1. Objects are not directly allocated in this generation; they are promoted from previous Gen 0 GCs. This counter is updated at the end of a GC; its not updated on every allocation.
5994=Gen 2 heap size
5995=This counter displays the current number of bytes in generation 2 (Gen 2). Objects are not directly allocated in this generation; they are promoted from Gen 1 during previous Gen 1 GCs. This counter is updated at the end of a GC; its not updated on every allocation.
5996=Large Object Heap size
5997=This counter displays the current size of the Large Object Heap in bytes. Objects greater than a threshold are treated as large objects by the Garbage Collector and are directly allocated in a special heap; they are not promoted through the generations. In CLR v1.1 and above this threshold is equal to 85000 bytes. This counter is updated at the end of a GC; it s not updated on every allocation.
5998=Finalization Survivors
5999=This counter displays the number of garbage collected objects that survive a collection because they are waiting to be finalized. If these objects hold references to other objects then those objects also survive but are not counted by this counter; the "Promoted Finalization-Memory from Gen 0" and "Promoted Finalization-Memory from Gen 1" counters represent all the memory that survived due to finalization. This counter is not a cumulative counter; its updated at the end of every GC with count of the survivors during that particular GC only. This counter was designed to indicate the extra overhead that the application might incur because of finalization.
6000=# GC Handles
6001=This counter displays the current number of GC Handles in use. GCHandles are handles to resources external to the CLR and the managed environment. Handles occupy small amounts of memory in the GCHeap but potentially expensive unmanaged resources.
6002=Allocated Bytes/sec
6003=This counter displays the rate of bytes per second allocated on the GC Heap. This counter is updated at the end of every GC; not at each allocation. This counter is not an average over time; it displays the difference between the values observed in the last two samples divided by the duration of the sample interval.
6004=# Induced GC
6005=This counter displays the peak number of times a garbage collection was performed because of an explicit call to GC.Collect. Its a good practice to let the GC tune the frequency of its collections.
6006=% Time in GC
6007=% Time in GC is the percentage of elapsed time that was spent in performing a garbage collection (GC) since the last GC cycle. This counter is usually an indicator of the work done by the Garbage Collector on behalf of the application to collect and compact memory. This counter is updated only at the end of every GC and the counter value reflects the last observed value; its not an average.
6008=Not Displayed
6009=Not Displayed.
6010=# Bytes in all Heaps
6011=This counter is the sum of four other counters; Gen 0 Heap Size; Gen 1 Heap Size; Gen 2 Heap Size and the Large Object Heap Size. This counter indicates the current memory allocated in bytes on the GC Heaps.
6012=# Total committed Bytes
6013=This counter displays the amount of virtual memory (in bytes) currently committed by the Garbage Collector. (Committed memory is the physical memory for which space has been reserved on the disk paging file).
6014=# Total reserved Bytes
6015=This counter displays the amount of virtual memory (in bytes) currently reserved by the Garbage Collector. (Reserved memory is the virtual memory space reserved for the application but no disk or main memory pages have been used.)
6016=# of Pinned Objects
6017=This counter displays the number of pinned objects encountered in the last GC. This counter tracks the pinned objects only in the heaps that were garbage collected e.g. a Gen 0 GC would cause enumeration of pinned objects in the generation 0 heap only. A pinned object is one that the Garbage Collector cannot move in memory.
6018=# of Sink Blocks in use
6019=This counter displays the current number of sync blocks in use. Sync blocks are per-object data structures allocated for storing synchronization information. Sync blocks hold weak references to managed objects and need to be scanned by the Garbage Collector. Sync blocks are not limited to storing synchronization information and can also store COM interop metadata. This counter was designed to indicate performance problems with heavy use of synchronization primitives.

These include both .NET exceptions and unmanaged exceptions that get converted into .NET exceptions e.g. null pointer reference exception in unmanaged code would get re-thrown in managed code as a .NET System.NullReferenceException; this counter includes both handled and unhandled exceptions. Exceptions should only occur in rare situations and not in the normal control flow of the program; this counter was designed as an indicator of potential performance problems due to large (>100s) rate of exceptions thrown. This counter is not an average over time; it displays the difference between the values observed in the last two samples divided by the duration of the sample interval.
6140=# of Filters / sec
6141=This counter displays the number of .NET exception filters executed per second. An exception filter evaluates whether an exception should be handled or not. This counter tracks the rate of exception filters evaluated; irrespective of whether the exception was handled or not. This counter is not an average over time; it displays the difference between the values observed in the last two samples divided by the duration of the sample interval.
6142=# of Finallys / sec
6143=This counter displays the number of finally blocks executed per second. A finally block is guaranteed to be executed regardless of how the try block was exited. Only the finally blocks that are executed for an exception are counted; finally blocks on normal code paths are not counted by this counter. This counter is not an average over time; it displays the difference between the values observed in the last two samples divided by the duration of the sample interval.
6144=Throw To Catch Depth / sec
6145=This counter displays the number of stack frames traversed from the frame that threw the .NET exception to the frame that handled the exception per second. This counter resets to 0 when an exception handler is entered; so nested exceptions would show the handler to handler stack depth. This counter is not an average over time; it displays the difference between the values observed in the last two samples divided by the duration of the sample interval.

1=1847
2=Système
3=L objet de performance Système inclut des compteurs qui s appliquent à plusieurs instances d un composant sur l ordinateur.
4=Mémoire
5=L objet de performances Mémoire inclut les compteurs qui décrivent le comportement de la mémoire réelle et virtuelle de l ordinateur. La mémoire physique est le montant de mémoire vive sur l ordinateur. La mémoire virtuelle est l espace en mémoire physique et sur le disque. La plupart de ces compteurs surveillent le mouvement des pages de code et de données entre le disque et la mémoire physique. Si celui-ci est trop important, indice d une mémoire insuffisante, cela peut provoquer des délais qui interfèrent avec les processus système.
6=% temps processeur
7=Le % Temps processeur est le pourcentage de temps que le processeur utilise pour exécuter des threads actifs. Il est calculé en mesurant le pourcentage de temps que le processeur passe à exécuter le thread inactif, puis en y soustrayant la valeur de 100 %. (Chaque processeur a un thread inactif qui consomme des cycles lorsque aucun autre thread n est prêt à s exécuter.) Ce compteur est l indicateur principal de l activité du processeur et affiche le pourcentage de temps sur l intervalle échantillon passé à faire un travail utile. Il est à noter que le calcul de l inactivité du système est effectué à un intervalle d échantillonnage interne basé sur l horloge système (10 minutes). Sur les processeurs rapides actuels, le % Temps processeur peut donc sous-estimer l utilisation du processeur, puisque celui-ci peut passer beaucoup de temps à servir les threads entre l intervalle d échantillonnage de l horloge système. Les applications de minutage basées sur la charge de travail sont un exemple d applications qui très probablement seront mal mesurées, puisque les minuteurs sont signalés juste après l échantillon.
9=Le % Temps DPC total est le pourcentage moyen de temps que tous les processeurs passent à recevoir et traiter des appels DPC. (Les appels DPC sont des interruptions qui s exécutent à un niveau de priorité inférieure par rapport aux interruptions standard). C est la somme des Processeur : % Temps DPC pour tous les processeurs sur l ordinateur, divisé par le nombre de processeurs. Système : % Temps DPC total est un composant de Système : % Temps total privilégié parce que les appels DPC sont exécutés en mode Privilégié. Les appels DPC sont comptés séparément et ne sont pas un composant du compte des interruptions. Ce compteur affiche le temps moyen d occupation comme un pourcentage du temps échantillon.
10=Opérations de lecture de fichier/s
11=Les Opérations de lecture de fichier/s sont la combinaison du taux de requêtes de lecture du système de fichiers à tous les périphériques de l ordinateur, y compris les requêtes de lecture à partir du cache du système de fichiers. Ce compteur est mesuré en nombre de lectures. Il affiche la différence entre les valeurs observées dans les deux derniers intervalles de temps, divisée par la durée de l intervalle échantillon.
12=Opérations d écriture de fichier/s
13=Les Opérations d écriture de fichier/s sont la combinaison du taux de requêtes d écriture du système de fichiers à tous les périphériques de l ordinateur, y compris les requêtes d écriture dans le cache du système de fichiers. Ce compteur est mesuré en nombre d écritures. Il affiche la différence entre les valeurs observées dans les deux derniers intervalles de temps, divisée par la durée de l intervalle échantillon.
14=Opérations de contrôle de fichier/s
15=Les Opérations de contrôle de fichier/s sont la combinaison du taux d opérations du système de fichiers qui ne sont ni écritures, ni lectures, telles que des requêtes de contrôle et d information sur les caractéristiques ou l état d un périphérique. C est l inverse de Système : Opérations de fichiers/s et ce compteur est mesuré en nombre d opérations par seconde. Il affiche la différence entre les valeurs observées dans les deux derniers intervalles de temps, divisée par la durée de l intervalle échantillon.
16=Octets lus sur fichier/s
17=Les Octets lus sur fichier/s sont le taux global auquel les octets sont lus pour satisfaire les requêtes de lecture du système de fichiers vers tous les périphériques de l ordinateur, y compris les lectures à partir du cache du système de fichiers. Ce compteur est mesuré en nombre d octets par seconde. Il affiche la différence entre les valeurs observées dans les deux derniers intervalles de temps, divisée par la durée de l intervalle échantillon.
18=Octets écrits sur fichier/s
19=Les Octets écrits sur fichier/s sont le taux global auquel les octets sont écrits pour satisfaire les requêtes d écriture du système de fichiers vers tous les périphériques de l ordinateur, y compris les écritures à partir du cache du système de fichiers. Ce compteur est mesuré en nombre d octets par seconde. Il affiche la différence entre les valeurs observées dans les deux derniers intervalles de temps, divisée par la durée de l intervalle échantillon.
20=Octets de contrôle de fichier/s
21=Les Octets de contrôle de fichier/s sont un cumul des octets transférés pour toutes les opérations sur le système de fichiers qui ne sont ni des lectures, ni des écritures. Ces opérations incluent généralement les requêtes de contrôle du système de fichiers ou les requêtes pour des informations sur les caractéristiques ou le statut des périphériques. Ce compteur affiche la différence entre les valeurs observées dans les deux derniers intervalles de temps, divisée par la durée de l intervalle échantillon.
23=% Temps d interruption total est le pourcentage moyen de temps passé par tous les processeurs à recevoir et à traiter des interruptions matérielles, où la valeur est un indicateur indirect de l activité des périphériques qui génèrent des interruptions. C est la somme des % Temps d interruption pour tous les processeurs de l ordinateur, divisée par le nombre de processeurs. Les DPC sont comptés séparément et ne sont pas considérés dans le compte des interruptions. Cette valeur est un indicateur indirect de l activité des périphériques qui génèrent des interruptions, tels que les horloges système, les cartes d interface réseau et d autres périphériques.
24=Octets disponibles
25=Les octets disponibles correspondent à la mémoire physique en octets immédiatement disponible pour une allocation à un processus ou pour une utilisation du système. Il s agit de la quantité de mémoire attribuée aux listes de pages vides et pages de zéros en attente (mises en cache).
26=Octets validés
27=Les Octets validés correspondent à la taille de la mémoire virtuelle dédiée en octets. La mémoire dédiée est la mémoire physique pour laquelle de l espace a été réservé dans le fichier d échange du disque. Il peut y avoir un ou plusieurs fichiers d échange sur chaque lecteur physique. Ce compteur affiche la dernière valeur observée seulement, ce n est pas une moyenne.
28=Défauts de page/s
29=Défauts de page/s est le nombre moyen de défauts de pages par secondes. Il est mesuré en nombre de défauts de page par seconde car seule une page est en erreur dans chaque opération, par conséquent c est également égal au nombre d opérations d erreurs de page. Ce compteur inclut à la fois les défauts matériels (ceux qui demandent un accès au disque) et les défauts logiciels (ceux pour lesquels la page concernée est trouvée ailleurs dans la mémoire physique). La plupart des processeurs peuvent gérer un nombre important de défauts logiciels sans conséquence. Toutefois, les défauts matériels, qui demandent davantage d accès au disque, peuvent entraîner des délais significatifs.
30=Limite de mémoire dédiée
31=La Limite de mémoire dédiée est la taille de la mémoire virtuelle qui peut être dédiée sans avoir à étendre le ou les fichiers d échange. Elle est mesurée en octets. (La mémoire dédiée est la mémoire physique pour laquelle l espace a été réservée sur les fichiers d échange des disques. Il peut y avoir un fichier d échange pour chaque disque logique). Si le ou les fichiers d échange doivent être étendus, la limite s accroît également. Ce compteur correspond à la dernière valeur observée seulement et non à une moyenne sur un intervalle de temps.
32=Copies pour écriture/s
33=Les Copies pour écriture/s sont le taux de défauts de page causés par des tentatives d écriture qui ont été satisfaits en effectuant une copie de la page depuis un emplacement autre que la mémoire physique. C est une façon économique de partager des données puisque la copie de la page n est effectuée que lorsqu une tentative d écriture intervient sur celle-ci sinon la page est partagée. Ce compteur affiche le nombre de copies, sans inclure le nombre de pages copiés au cours de chaque opération.
34=Défauts en transit/s
35=Les Défauts en transit/s sont la vitesse à laquelle les défauts de page sont résolus en récupérant les pages qui étaient en cours d utilisation par un autre processus partageant la page ou qui étaient sur la liste des pages modifiées, ou la liste des pages en attente ou en train d être écrites sur le disque au moment du défaut de page. Les pages ont été récupérées sans activité supplémentaire du disque. Les défauts en transit sont comptés en nombre de défauts ; ce nombre est également égal au nombre de pages en erreur car seule une page est en erreur par opération.
36=Défauts de cache/s
37=Les Défauts de cache/s sont le nombre de défauts qui surviennent lorsqu une page du cache du système de fichiers n y est pas trouvée et doit être récupérée autre part dans la mémoire (défaut peu important) où à partir du disque (défaut important). Le cache du système de fichiers est une zone de mémoire physique qui stocke les pages de données récemment utilisées par les applications. L activité du cache est un indicateur fiable de la plupart des opérations d E/S des applications. Ce compteur dénombre les défauts, sans considérer le nombre de pages défectueuses dans chaque opération.
38=Défauts de page à zéro/s
39=Les Défauts de page à zéro/s sont le nombre de défauts de page pour des pages qui doivent être initialisées à zéro afin de satisfaire la demande. Les pages initialisées à zéro, qui sont vidées et remplies de zéros, constituent une fonctionnalité de sécurité de Windows NT. Elles évitent les processus de voir les données enregistrées par des processus précédents qui utilisaient de l espace mémoire. Windows NT maintient une liste de pages à zéro pour accélérer ce processus. Ce compteur dénombre les défauts, sans considérer le nombre de pages récupérées pour satisfaire le défaut. Il affiche la différence entre les valeurs observées dans les deux derniers intervalles de temps, divisée par la durée de l intervalle échantillon.
40=Pages/s
41=Les Pages/s sont la vitesse à laquelle les pages sont lues à partir du disque ou écrites sur le disque afin de résoudre des défauts de page matériels. Ce compteur a été créé pour indiquer le type de fautes qui causent des délais au niveau du système. C est la somme des pages entrées/s et des pages sorties/s de l objet Mémoire. Cette somme est le nombre de pages, pour pouvoir être comparée à d autres comptes de pages, tels que Défauts de page/s sans conversion. Ce compteur inclut le trafic des pages pour le compte du cache système afin d accéder aux données des fichiers pour les applications. Cette valeur inclut aussi les pages de et vers des fichiers de mémoire mappée non cachés.
42=Lectures de pages/s
43=Les Lectures de pages/s sont la vitesse à laquelle le disque a été lu pour résoudre les défauts de page matériels. Il affiche le nombre d opérations de lecture, sans considération du nombre de pages récupérées par chaque opération. Un défaut de page matériel se produit lorsqu un processus fait référence à une page dans la mémoire virtuelle qui n est ni dans son jeu de pages de travail, ni ailleurs en mémoire physique, et qui doivent être récupérés à partir du disque. Ce compteur est indicateur principal du type de fautes qui causent des délais au niveau du système. Il inclut les opérations de lecture pour corriger les erreurs dans le cache du système de fichiers (généralement requis par les applications). et aussi les pages lues à partir des fichiers de mémoire mappée non cachés. Comparer la valeur de Mémoire\Pages entrantes/s pour déterminer le nombre moyen de pages lues pendant chaque opération.
44=Longueur de la file du processeur
45=La Longueur de la file du processeur est le nombre de threads dans la file du processeur. À la différence des compteurs disque, ce compteur ne dénombre que les threads prêtes et non les threads en cours d exécution. Il n y a qu une seule file pour le temps processeur, même sur les ordinateurs avec plusieurs processeurs. Par conséquent, si un ordinateur a plusieurs processeurs, vous devez diviser cette valeur par le nombre de processeurs s occupant de cette charge de travail. Une file de processeurs maintenue à moins de 10 threads par processeur est normalement acceptable, selon la charge de travail.
46=État de la thread
47=L État du thread est l état courant du thread. Il s agit de 0 pour initialisé, 1 pour prêt, 2 pour en exécution, 3 pour actif, 4 pour terminé, 5 pour en attente, 6 pour en transition, 7 pour état inconnu. Un thread en exécution utilise un processeur ; un thread actif va en utiliser un. Un thread prêt veut utiliser un processeur, mais attend car aucun n est libre. Un thread en transition attend une ressource afin de s exécuter, telle qu attendre que la pile d exécution soit remise en mémoire depuis le fichier d échange. Un thread en attente n a pas besoin de processeur car il attend la fin d une opération sur un périphérique ou la libération d une ressource.
48=Pages en sortie/s
49=Pages en sortie/s sont la vitesse à laquelle les pages sont écrites sur le disque pour libérer de la mémoire physique. Les pages sont écrites sur le disque seulement si elles ont été modifiées en mémoire physique, car elles contiennent vraisemblablement des données plutôt que du code. Un taux élevé de pages en sortie peut indiquer un manque de mémoire. Windows écrit plus de pages sur le disque pour libérer de l espace lorsque la mémoire physique commence à manquer. Ce compteur affiche les pages et peut être comparé à d autres nombres de pages, sans conversion.
50=Écritures de pages/s
51=Les Écritures de pages/s sont le nombre de fois que des pages ont été écrites sur le disque pour libérer de la mémoire physique. Les pages sont écrites sur le disque seulement si elles ont été modifiées en mémoire physique, car elles contiennent vraisemblablement des données plutôt que du code. Ce compteur dénombre les opérations d écriture, sans considérer le nombre de pages écrites à chaque opération. Il affiche la différence entre les valeurs observées dans les deux derniers intervalles de temps, divisée par la durée de l intervalle échantillon.
52=Navigateur
53=L objet de performance de l Explorateur regroupe les compteurs qui mesurent les taux d annonces, d énumérations et d autres transmissions de l explorateur.
54=Serveur d annonces
55=Serveur d annonces est le taux auquel les serveurs dans ce domaine se sont annoncés eux-mêmes à ce serveur.
56=Octets de réserve paginée
57=Les Octets de réserve paginée sont le nombre d octets dans la réserve paginée, une zone de la mémoire virtuelle système utilisée pour les objets qui peuvent être écrits sur le disque lorsqu ils ne sont pas utilisés. La valeur Octets de réserve paginée de l objet Mémoire n est pas calculée comme la valeur Octets de réserve paginée de l objet Processus et peut donc être différente de la valeur Octets de réserve paginée de l objet Processus(_Total). Ce compteur correspond à la dernière valeur observée seulement et non à une moyenne sur un intervalle de temps.
58=Octets de réserve non paginée
59=Les Octets de réserve non paginée sont le nombre d octets dans la réserve non paginée, une zone de la mémoire virtuelle système utilisée pour les objets qui ne peuvent pas être écrits sur le disque mais qui doivent rester en mémoire physique tant qu ils sont alloués. La valeur Octets de réserve non paginée de l objet Mémoire n est pas calculée comme la valeur Octets de réserve non paginée de l objet Processus et peut donc être différente de la valeur Octets de réserve non paginée de l objet Processus(_Total). Ce compteur correspond à la dernière valeur observée seulement et non à une moyenne sur un intervalle de temps.
60=Allocations de réserve paginée
61=Les Allocations de réserve paginée sont le nombre d appels d allocation d espace dans la réserve paginée. La réserve paginée est une zone de la mémoire virtuelle système utilisée pour les objets qui peuvent être écrits sur le disque lorsqu ils ne sont pas utilisés. Ce compteur est mesuré en nombre d appels, sans considérer la quantité d espace alloué à chaque appel. Ce compteur correspond à la dernière valeur observée seulement et non à une moyenne sur un intervalle de temps.
63=Les Octets résidents de réserve paginée sont le nombre d octets de la partie de réserve paginée, qui résident actuellement de manière active en mémoire physique. La réserve paginée est une zone de la mémoire virtuelle système utilisée pour les objets qui peuvent être écrits sur le disque lorsqu ils ne sont pas utilisés. Ce compteur correspond à la dernière valeur observée seulement et non à une moyenne sur un intervalle de temps.
64=Allocations de réserve non paginée
65=Les Allocations de réserve non paginée sont le nombre d appels en vue d allouer de l espace dans la réserve non paginée. La réserve non paginée est une zone de mémoire système pour les objets qui ne peuvent pas être écrits sur le disque, mais qui doivent rester en mémoire physique tant qu ils sont alloués. Ce compteur est mesuré en nombre d appels, sans considérer la quantité d espace alloué à chaque appel. Ce compteur correspond à la dernière valeur observée seulement et non à une moyenne sur un intervalle de temps.
66=Octets résidants de réserve paginée
67=Le Total des octets/s est la vitesse totale d envoi ou de réception des octets sur le réseau par le protocole, mais uniquement pour les trames (les paquets) qui contiennent des données. Cela correspond à la somme des Octets de trame/s et des Octets de datagrammes/s.
68=Total des octets dans le code système
69=Le Total des octets dans le code système est le nombre d octets de code du système d exploitation paginable mappés actuellement à l espace d adressage virtuel du système. Cette valeur est calculée en faisant la somme des octets dans Ntoskrnl.exe, Hal.dll, les pilotes de démarrage et les fichiers système chargés par Ntldr/osloader. Ce compteur n inclut pas le code qui doit rester en mémoire physique et ne peut pas être écrit sur le disque. Ce compteur correspond à la dernière valeur observée seulement et non à une moyenne sur un intervalle de temps.
70=Octets résidants dans le code système
71=Les Octets résidents dans le code système sont le nombre d octets de code du système d exploitation paginable, qui résident actuellement de manière active en mémoire physique. Cette valeur est un composant de Total des octets dans le code système de l objet Mémoire. Les octets résidents dans le code système de l objet Mémoire (et le total des octets dans le code système de l objet Mémoire) n incluent pas le code qui doit rester en mémoire physique et ne peut pas être écrit sur le disque. Ce compteur correspond à la dernière valeur observée seulement et non à une moyenne sur un intervalle de temps.
72=Total des octets dans le pilote système
73=Le Total des octets dans le pilote système est la taille en octets de la mémoire virtuelle paginable actuellement utilisé par les pilotes des périphériques. (La mémoire paginable peut être écrite sur le disque lorsqu elle n est pas utilisée). Ce compteur inclut la mémoire physique (Octets résidents dans le pilote système de l objet Mémoire) ainsi que le code et les données paginés sur le disque. C est un composant du total des octets dans le code système de l objet Mémoire. Ce compteur correspond à la dernière valeur observée seulement et non à une moyenne sur un intervalle de temps.
74=Octets résidants dans le pilote système
75=Les Octets résidants dans le pilote système sont le nombre d octets de mémoire physique paginable actuellement utilisé par les pilotes des périphériques. C est le jeu de pages de travail (zone de mémoire physique) des pilotes. Cette valeur est un composant du total des octets dans le code système de l objet Mémoire, qui inclut également la mémoire des pilotes qui a été écrite sur le disque. Ni les octets résidants dans le pilote système, ni le total des octets dans le pilote système n incluent la mémoire qui ne peut pas être écrite sur le disque.
76=Octets résidants dans le cache système
77=Les Octets résidents dans le code système sont le nombre d octets de la partie du cache de fichiers système, qui résident actuellement de manière active en mémoire physique. Les compteurs Octets résidents dans le cache système et Octets du cache de l objet Mémoire sont équivalents. Ce compteur correspond à la dernière valeur observée seulement et non à une moyenne sur un intervalle de temps.

84=Requêtes de la liste du serveur/s
85=Requêtes de la liste du serveur/s sont le nombre de requêtes pour retrouver une liste de serveurs explorateurs qui a été traitée par cette station de travail.
86=Cache
87=L objet de performance Cache regroupe les compteurs qui surveillent le cache du système de fichiers, une zone de mémoire physique qui stocke les données utilisées récemment tant que cela est possible pour permettre l accès aux données sans avoir à lire sur le disque. Parce que les applications utilisent le cache, il est observé comme indicateur des opérations d E/S des applications. Lorsque la mémoire est abondante, le cache peut grossir, mais si elle devient rare, le cache peut devenir insuffisant pour être efficace.

142=% temps utilisateur
143=% temps utilisateur est le pourcentage du temps passé par le processeur en mode Utilisateur. (Le mode Utilisateur est un mode de traitement restreint conçu pour les applications, les sous-systèmes d environnement et les sous-systèmes intégraux. Le mode Privilégié, alternatif, est prévu pour les composants du système d exploitation et permet l accès direct au matériel et à toute la mémoire. Le système d exploitation exécute les threads d application en mode Privilégié pour accéder aux services du système d exploitation). Ce compteur affiche le temps moyen d occupation en tant que pourcentage de l intervalle échantillonné.
144=% temps privilégié
145=% temps privilégié est le pourcentage du temps écoulé passé par les threads de processus à exécuter du code en mode Privilégié. Lorsqu un service système Windows est appelé, le service s exécute souvent en mode privilégié afin d obtenir l accès aux données privées du système. Les threads s exécutant en mode Utilisateur n ont pas accès à de telles données. Les appels système peuvent être explicites ou implicites tels que les défauts de page et les interruptions. À l inverse de certains anciens systèmes d exploitation, Windows utilise les frontières de processus pour la protection des sous-systèmes en plus de la protection traditionnelle apportée par l utilisation des modes Utilisateur et Privilégié. Ces processus de sous-système apportent une protection supplémentaire. Ainsi, certains travaux effectués par Windows NT pour le compte de votre application peuvent apparaître dans d autres processus de sous-système en plus du temps privilégié pour votre processus.
146=Changements de contexte/s
147=Les Changements de contexte/s sont le taux combiné auquel tous les processeurs de l ordinateur commutent d un thread à un autre.

Cette valeur est un indicateur indirect de l activité des périphériques tels que l horloge système, la souris, les pilotes de disque, les lignes de communication de données, les cartes d interface réseau et d autres périphériques. Ces périphériques interrompent normalement le processeur quand ils ont fini une tâche ou qu ils ont besoin d assistance. L exécution d une thread normale est interrompue. L horloge système interrompt le processeur toutes les 10 millisecondes, créant un arrière-plan à l activité de l interruption. Ce compteur affiche la différence entre les valeurs observées dans les deux derniers échantillons, divisé par la durée de l intervalle d échantillon.
150=Appels système/s
151=Les Appels système/s sont le taux combiné des appels aux routines de services système de Windows NT par tous les processus s exécutant sur l ordinateur.

157=Le % Temps Utilisateur est le pourcentage du temps écoulé que les threads de processus passent à exécuter le code en mode utilisateur. les applications, les sous-systèmes (d environnement et intégraux) s exécutent en mode Utilisateur. L exécution du code en mode utilisateur ne peut pas endommager l intégrité de l exécutif Windows, du noyau et des pilotes de périphériques. A l inverse de certains anciens systèmes d exploitation, Windows utilise les frontières de processus pour la protection des sous-systèmes en plus de la protection traditionnelle apportée par l utilisation des modes Utilisateur et Privilégiés. Certains travaux effectués par Windows pour le compte de votre application peuvent apparaître dans d autres processus de sous-système en plus du temps privilégié pour le processus.
158=Énumérations du domaine/s
159=Le % Temps privilégié est le pourcentage du temps écoulé passé par les threads de processus à exécuter du code en mode Privilégié.

177=Les Défauts de page/s sont le taux de défauts de page générés par les threads s exécutant dans ce processus. Un défaut de page intervient lorsqu un processus fait référence à une page de mémoire virtuelle qui ne se trouve pas dans son jeu de pages de travail en mémoire centrale. Un défaut de page n exécutera pas la recherche sur disque si cette page est dans la liste En attente, et donc déjà en mémoire centrale, ou si elle est utilisée par un autre processus avec lequel la page est partagée.
178=Plage de travail max.
179=Plage de travail max. est le nombre maximal d octets qu il y a eu dans la plage de travail de ce processus à un moment donné. La plage de travail est l ensemble de pages mémoire touchées récemment par les threads de ce processus. Si la mémoire disponible de l ordinateur est au-dessus d un seuil, les pages sont laissées dans la plage de travail d un processus même si elles ne sont pas utilisées. Lorsque la mémoire disponible tombe en dessous d un seuil, les pages sont retirées de la plage de travail. Si elles s avèrent nécessaires, elles seront ramenées après un défaut de page logiciel dans la plage de travail avant qu elles ne quittent la mémoire centrale.

183=Fichier d échange (octets) est le nombre maximal de mémoire virtuelle que ce processus a réservé pour une utilisation dans les fichiers d échange. Les fichiers d échange sont employés pour stocker des pages mémoire utilisées par le processus et qui ne sont pas contenues dans d autres fichiers. Le fichier d échange est utilisé par tous les processus, et un manque de place dans le fichier d échange peut empêcher les autres processus d allouer de la mémoire. S il n y a pas de fichiers d échange, ce compteur représente la quantité maximale de mémoire virtuelle que le processus a réservée pour une utilisation dans la mémoire physique.
184=Fichier d échange (octets)
185=Fichier d échange (octets) est la quantité actuelle de mémoire virtuelle, en octets, que ce processus a réservé pour une utilisation dans les fichiers d échange. Les fichiers d échange sont employés pour stocker des pages mémoire utilisées par le processus et qui ne sont pas contenues dans d autres fichiers.

Le code exécuté pour gérer des interruptions dues au matériel et gérer des conditions de déroutement est inclus dans ce compte.
193=Le % Temps utilisateur est le pourcentage du temps processeur passé en mode Utilisateur dans des threads actifs. Tout le code des applications et des sous-systèmes (d environnement et intégraux) s exécute en mode Utilisateur. Le moteur graphique, les pilotes de périphériques graphiques et le gestionnaire de fenêtres s exécutent aussi en mode Utilisateur. Le code s exécutant en mode Utilisateur ne peut pas mettre en danger l intégrité de l exécutif Windows NT, du noyau ou des pilotes de périphériques. À l inverse de certains anciens systèmes d exploitation, Windows NT utilise les frontières de processus pour la protection des sous-systèmes en plus de la protection traditionnelle apportée par l utilisation des modes Utilisateur et Privilégié.

Ainsi, certains travaux effectués par Windows NT pour le compte de votre application peuvent apparaître dans d autres processus de sous-système en plus du temps privilégié pour votre processus.
197=Les Changements de contexte/s sont le taux de commutations d une thread à une autre. Les commutations de threads peuvent survenir soit à l intérieur d un même processus, soit entre processus différents. Une commutation de threads peut être causée soit par une thread demandant des informations à une autre, soit lorsqu une thread est préemptée par une autre thread prête à s exécuter et de priorité supérieure. A l inverse de certains anciens systèmes d exploitation, Windows NT utilise les frontières de processus pour la protection des sous-systèmes en plus de la protection traditionnelle apportée par l utilisation des modes Utilisateur et Privilégié. Ces processus de sous-système apportent une protection supplémentaire. Ainsi, certains travaux effectués par Windows NT pour le compte de votre application peuvent apparaître dans d autres processus de sous-système en plus du temps privilégié pour votre processus. La commutation vers le processus du sous-système engendre un changement de contexte pour la thread de l application. Le retour à l application engendre un autre changement de contexte dans la thread du sous-système.
198=Taille de file d attente du disque actuelle
199=La Taille de file d attente du disque actuelle est le nombre de requêtes en attente du disque au moment où le sondage de performance est effectué. Cela inclut les requêtes servies au moment du sondage. C est une longueur instantanée, et non pas une moyenne sur un intervalle de temps. Les lecteurs ayant plusieurs piles de disque peuvent avoir plusieurs requêtes actives en même temps, mais les autres requêtes concurrentes doivent attendre pour être servies. Ce compteur peut représenter une grande ou une petite file transitoire, mais s il y a une charge soutenue sur le lecteur de disque, il est probable qu elle soit constamment grande. Les requêtes subissent des retards proportionnels à la longueur de cette file moins le nombre de piles de disques des lecteurs. Cette différence devrait être en moyenne inférieure à deux pour conserver de bonnes performances.

Le processeur est la partie de l ordinateur qui réalise les calculs logiques et arithmétiques, qui lance les opérations sur les périphériques et qui exécute les threads des processus. Un ordinateur peut avoir plusieurs processeurs. L objet Processeur représente chaque processeur comme une instance de l objet.
240=Pourcentage de temps total du processeur
241=Le % Temps total du processeur est le pourcentage moyen de temps calculé sur tous les processeurs de l ordinateur pendant lequel ces processeurs exécutent des threads actifs. Ce compteur a été créé pour indiquer l activité du processeur sur les ordinateurs multiprocesseurs. Il est égal à la somme des % Temps processeur de l objet Processus pour tous les processeurs, divisée par le nombre de processeurs. Il est calculé en faisant la somme des temps que tous les processeurs passent à exécuter le thread du processus inactif sur chaque intervalle échantillon, puis en soustrayant cette valeur à 100 % et en divisant la différence par le nombre de processeurs sur l ordinateur. (Chaque processeur a un thread inactif qui consomme des cycles lorsque aucun autre thread n est prêt à s exécuter.) Par exemple, sur un ordinateur multiprocesseur, une valeur de 50 % signifie que tous les processeurs sont occupés sur tout l intervalle échantillon. Ce compteur affiche le pourcentage moyen de temps d occupation observé sur l intervalle échantillon. Il est calculé en surveillant la durée d inactivité du service et en soustrayant cette valeur de 100 %.

L alternative, le mode Privilégié, est prévu pour les composants du système d exploitation et permet d accéder directement au matériel et à toute la mémoire. Le système d exploitation commute les threads d application dans le mode Privilégié pour accéder aux services du système d exploitation). Ce compteur affiche le temps moyen d occupation comme un pourcentage du temps échantillon.
244=Pourcentage de temps total privilégié
245=Le % Temps total Privilégié est le pourcentage moyen de temps d activité que passent tous les processeurs en mode noyau privilégié. C est la somme de % Temps Privilégié de l objet Processeur pour tous les processeurs de l ordinateur, divisée par le nombre de processeurs. La somme de % Temps total Utilisateur et de % Temps total Privilégié de l objet Système égale le % Temps total du processeur, mais pas toujours 100%. (Le mode Privilégié est un mode de traitement conçu pour les composants du système d exploitation qui permet d accéder directement au matériel et à toute la mémoire. Le système d exploitation commute les threads d application dans le mode Privilégié pour accéder aux services du système d exploitation. L alternative, le mode Utilisateur, est un mode restreint de traitement conçu pour les applications, les sous-systèmes d environnement et les sous-systèmes intégraux). Ce compteur affiche le temps moyen d occupation comme un pourcentage du temps.
246=Total des interruptions/s
247=Le Total des interruptions/s est le taux combiné d interruptions matérielles reçues et traitées par tous les processeurs de l ordinateur. C est la somme de Interruptions/s de l objet Processeur pour tous les processeurs, divisée par le nombre de processeurs ; ce compteur est mesuré en nombre d interruptions. Il n inclut pas les DPC, qui sont comptés séparément. Cette valeur est un indicateur indirect de l activité des périphériques qui génèrent des interruptions, tels que l horloge système, la souris, les pilotes de disque, les lignes de communication de données, les cartes d interface réseau et d autres périphériques. Ces périphériques interrompent normalement le processeur lorsqu ils ont terminé une tâche ou demandent de l assistance. La plupart des horloges système interrompent le processeur toutes les 10 millisecondes, créant un fond d activité d interruption. Ce compteur affiche la différence entre les valeurs observées dans les deux derniers intervalles de temps, divisée par la durée de l intervalle échantillon.
248=Processus
249=Le processus est le nombre de processus dans l ordinateur au moment du sondage. Notez que ceci constitue un décompte instantané et non pas une moyenne sur un intervalle de temps. Chaque processus représente l exécution d un programme.
250=Threads
251=Les Threads sont le nombre de threads dans l ordinateur au moment du sondage. Notez que ceci constitue un décompte instantané et non pas une moyenne sur un intervalle de temps. Une thread est l entité exécutable de base pouvant exécuter des instructions sur un processeur.
252=Événements
253=Les Événements sont le nombre d événements dans l ordinateur au moment du sondage. Notez que ceci constitue un décompte instantané et non pas une moyenne sur un intervalle de temps. Un événement est employé lorsque deux threads ou plus veulent synchroniser leur exécution.
254=Sémaphores
255=Les Sémaphores sont le nombre de sémaphores dans l ordinateur au moment du sondage. Notez que ceci constitue un décompte instantané et non pas une moyenne sur un intervalle de temps. Les threads emploient les sémaphores pour obtenir un accès exclusif momentané aux structures de données qu elles partagent avec d autres threads.
256=Mutex
257=Les Mutex sont le nombre de mutex dans l ordinateur au moment du sondage. Notez que ceci constitue un décompte instantané et non pas une moyenne sur un intervalle de temps. Les mutex sont employés par les threads pour s assurer qu une seule thread exécute une certaine section de code.
258=Sections
259=Les Sections sont le nombre de sections dans l ordinateur au moment du sondage. Notez que ceci constitue un décompte instantané et non pas une moyenne sur un intervalle de temps.

264=Octets reçus/s
265=Les Octets reçus/s sont le taux d octets arrivant dans le redirecteur depuis le réseau. Ceci inclut les données des applications aussi bien que les informations pour le protocole du réseau (comme les en-têtes de paquets).
266=Paquets reçus/s
267=Les Paquets reçus/s sont le taux auquel le Redirecteur reçoit des paquets (aussi appelés SMB pour 'Server Message Block'). Les transmissions réseau sont effectuées par paquets. Le nombre moyen d octets reçus dans un paquet peut être obtenu en divisant les octets reçus/s par ce compteur. Certains paquets reçus peuvent ne pas contenir de données, par exemple un accusé de réception pour une écriture effectuée par le Redirecteur compte pour un paquet reçu.
268=Lecture de pagination, octets/s
269=La Lecture de pagination, octets/s est le taux auquel le Redirecteur tente de lire les octets en réponse à des défauts de page. Les défauts de page sont provoqués par le chargement de modules (comme des programmes ou des bibliothèques), par un manque dans le cache (voir Lecture du cache, octets/s), ou par des fichiers directement mappés dans l espace d adressage des applications (une fonctionnalité très performante de Windows NT).
270=Lecture non paginée, octets/s
271=La Lecture non paginée, octets/s correspond aux octets lus par le Redirecteur en réponse à des requêtes fichier normales de la part d une application lorsqu elles sont redirigées pour provenir d un autre ordinateur. En plus des requêtes fichier, ce compteur inclut d autres méthodes de lecture à travers le réseau, telles que les canaux nommés ou les transactions. Ce compteur ne décompte pas les informations nécessaires aux protocoles réseau, mais seulement les données pour les applications.
272=Lecture du cache, octets/s
273=La Lecture du cache, octets/s est le taux auquel les applications accèdent au cache du système de fichiers en employant le Redirecteur. Certaines des ces requêtes de données sont satisfaites en récupérant les données sur le cache. Les requêtes manquantes dans le cache génèrent un défaut de page (voir Lecture de pagination, octets/s).
274=Lecture réseau, octets/s
275=La Lecture réseau, octets/s est le taux auquel vos applications lisent des données à travers le réseau. Cela se produit lorsque les données cherchées dans le cache du système de fichiers ne sont pas trouvées et doivent être récupérer sur le réseau. Si vous divisez cette valeur par Octets reçus/s, vous obtenez la proportion de données de l application provenant du réseau puisque (voir Octets reçus/s).
276=Octets transmis/s
277=Les Octets transmis/s sont le taux auquel les octets quittent le Redirecteur vers le réseau. Cela inclut toutes les données des applications aussi bien que les informations du protocole réseau (telles que les en-têtes de paquets).
278=Paquets transmis/s
279=Les Paquets transmis/s sont le taux auquel le Redirecteur envoie des paquets (aussi appelés SMB pour 'Server Message Blocks). Les transmissions réseau sont effectuées par paquets. Le nombre moyen d octets reçu dans un paquet peut être obtenu en divisant les Octets transmis/s par ce compteur.
280=Écriture de pagination, octets/s
281=L Écriture de pagination, octets/s est le taux auquel le Redirecteur tente d écrire les octets modifiés dans les pages utilisées par les applications. Les données modifiées par des modules (tels que les programmes ou les bibliothèques) qui ont été chargés sur le réseau sont écrites sur le fichier d échange lorsque l on a plus besoin d elles. Les autres pages sortantes proviennent du cache du système de fichiers (voir Écriture cache, octets/s).
282=Écriture non paginée, octets/s
283=L Écriture non paginée, octets/s est le taux auquel les octets sont écrits par le Redirecteur en réponse à des requêtes fichier normales de la part de l application lorsqu elles sont redirigées vers un autre ordinateur.

Ce compteur ne décompte pas les informations nécessaires aux protocoles réseau, mais seulement les données pour les applications.
284=Écriture du cache, octets/s
285=L Écriture du cache, octets/s est le taux auquel les applications de votre ordinateur accèdent au cache du système de fichiers en utilisant le Redirecteur. Les données peuvent ne pas quitter votre ordinateur immédiatement ; elles peuvent être conservées dans le cache pour continuer d être modifiées avant d être écrites sur le réseau. Cela économise du trafic réseau. Chaque écriture d un octet dans le cache est comptée ici.
286=Écriture réseau, octets/s
287=L Écriture réseau, octets/s est le taux auquel vos applications écrivent des données à travers le réseau. Cela se produit lorsque le cache du système de fichiers est contourné, comme pour les canaux nommés ou les transactions, ou lorsque le cache a écrit les octets sur le disque pour faire de la place à d autres données. Si vous divisez ce nombre par Octets reçus/s, vous obtenez la proportion de données de l application sur le réseau (voir Octets reçus/s).
288=Opérations de lecture/s
289=Les Opérations de lecture fichier/s sont le taux auquel les applications demandent au Redirecteur des données. Chaque appel à un système de fichier ou à une interface de programme d application (API) similaire compte pour une opération.
290=Lecture sélective, opérations/s
291=La Lecture sélective, opérations/s est le taux auquel les lectures sont faites, fichier par fichier, de façon non séquentielle. Si une lecture est effectuée en employant un handle de fichier particulier, suivie ensuite d une autre lecture qui ne soit pas parmi les octets suivants immédiatement contigus, ce compteur est incrémenté de un.
292=Paquets lus/s
293=Les Paquets lus/s sont le taux auquel les lectures sont placées sur le réseau. Chaque fois qu un paquet est envoyé avec une requête pour lire des données à distance, ce compteur est incrémenté de un.
294=Grosses lectures/s
295=Les Grosses lectures/s sont le taux auquel les lectures de plus de 2 fois la taille de la zone tampon allouée au serveur sont effectuées par les applications. Trop de lectures de ce genre peuvent entraîner des tensions autour des ressources du serveur. Ce compteur est incrémenté de un à chaque lecture. Il ne compte pas les paquets.
296=Petites lectures/s
297=Les Petites lectures/s sont le taux auquel des lectures de moins d un quart de la taille de la zone tampon allouée au serveur sont effectuées par les applications. Trop de lectures de ce genre peuvent indiquer un gaspillage des zones tampon du serveur. Ce compteur est incrémenté de un à chaque lecture. Il ne compte pas les paquets.
298=Opérations d écriture fichier/s
299=Les Opérations d écriture fichier/s sont le taux auquel les applications envoient des données au Redirecteur. Chaque appel à un système de fichier ou à une interface de programme d application (API) similaire compte pour une opération.

306=Petites écritures, paquets/s
307=Les Petites écritures, paquets/s sont le taux auquel des écritures de moins d un quart de la taille de la zone tampon allouée au serveur sont effectuées par les applications. Trop d écritures de ce genre peuvent indiquer un gaspillage des zones tampon du serveur. Ce compteur est incrémenté de un à chaque écriture. Il ne compte pas les paquets.
308=Lectures refusées/s
309=Les Lectures refusées/s sont le taux auquel le serveur ne peut pas accorder de requêtes de lectures brutes. Lorsqu une lecture est bien plus importante que la taille de la zone tampon du serveur, le Redirecteur demande une lecture brute qui, si elle est accordée, permettrait de transférer les données sans perdre trop de temps en protocole pour chaque paquet. Pour réaliser cela, le serveur doit bloquer les autres requêtes, de sorte que cette requête est refusée si le serveur est très occupé.
310=Écritures refusées/s
311=Les Écritures refusées/s sont le taux auquel le serveur ne peut pas accorder de requêtes d écritures brutes. Lorsqu une écriture est bien plus importante que la taille de la zone tampon du serveur, le Redirecteur demande une écriture brute qui, si elle est accordée, permettrait de transférer les données sans perdre trop de temps en protocole pour chaque paquet. Pour réaliser cela, le serveur doit bloquer les autres requêtes, de sorte que cette requête est refusée si le serveur est très occupé.
312=Erreurs réseau/s
313=Les Erreurs réseau/s sont la vitesse à laquelle les erreurs sérieuses et inattendues se produisent. De telles erreurs indiquent généralement que le redirecteur et un ou plusieurs serveurs ont d importantes difficultés de communication. Par exemple, une erreur de protocole SMB (Bloc de gestion du serveur) est une erreur réseau. Une entrée est également écrite dans le journal système des événements et fournit plus de précisions.
314=Sessions serveur
315=Les Sessions serveur comptent le nombre d objets de sécurité que le Redirecteur a gérés. Par exemple, une ouverture de session sur un serveur suivie d un accès réseau au même serveur établira une seule connexion, mais deux sessions.

La valeur est 0 ou 7 lorsque la thread attend l exécutif, 1 ou 8 pour une page libre, 2 ou 9 pour un page entrante (Page In), 3 ou 10 pour une allocation de la réserve, 4 ou 11 pour une pause d exécution, 5 ou 12 pour un état suspendu, 6 ou 13 pour une requête utilisateur, 14 pour une paire d événements hauts, 15 pour une paire d événements bas, 16 pour un reçu d un appel de procédure local (LPC), 17 pour une réponse de LPC, 18 pour la mémoire virtuelle et 19 pour une page sortante (Page Out); 20 et plus ne sont pas encore assignés. Les paires d événements sont employés pour communiquer avec les sous-systèmes protégés (voir Commutations de contextes).
339=Le % Temps DPC est le pourcentage de temps que le processeur passe à recevoir et à traiter des appels de procédures différés (DPC). Les DPC sont des interruptions qui s exécutent à un niveau de priorité plus bas que les interruptions standard. Le % Temps DPC est un composant du % Temps privilégié puisque les DPC sont exécutés en mode Privilégié. Ils sont comptés séparément et ne font pas partie des compteurs d interruptions. Ce compteur affiche le temps moyen d occupation comme un pourcentage du temps échantillon.
340=Sessions fermées pour inactivité

342=Sessions fermées suite à une erreur
343=Nombre de sessions fermées suite à une erreur inattendue ou sessions qui ont dépassé le délai de déconnexion automatique et ont été fermées normalement. La valeur de délai de déconnexion automatique représente le nombre de secondes pendant lesquelles les connexions inactives sans session associée sont conservées avant d être déconnectées automatiquement par un serveur. La valeur par défaut est de 30 secondes. Ce compteur est incrémenté en raison d une opération normale du serveur et non pas en tant qu indication de problèmes réseau ou d une erreur inattendue.
344=Sessions fermées normalement
345=Les Sessions fermées normalement sont le nombre de sessions qui se sont terminées normalement. Utile pour interpréter les chiffres de sessions fermées en raison d inactivité et de sessions fermées suite à une erreur. Ce nombre permet d établir des pourcentages.
