ProcessPerfDataInfo Properties

Gets or sets the description.

Gets or sets the elapsed time.

Win32_PerfFormattedData_PerfProc_Process: Total number of handles that the process has open. This number is the sum of the handles currently opened by each thread in the process.

Gets or sets the ID process.

Win32_PerfFormattedData_PerfProc_Process: Rate at which the process is reading and writing bytes in I/O operations. This property counts all I/O activity generated by the process, including file, network, and device I/O operations.

Win32_PerfFormattedData_PerfProc_Process: Rate at which the process is issuing read and write I/O operations. This property counts all I/O activity generated by the process, including file, network, and device I/O operations.

Win32_PerfFormattedData_PerfProc_Process: Rate at which the process is issuing bytes to I/O operations that do not involve data such as control operations. This property counts all I/O activity generated by the process, including file, network, and device I/O operations.

Win32_PerfFormattedData_PerfProc_Process: Rate at which the process is issuing I/O operations that are neither read nor write operations. An example of this type of operation would be a control function. This property counts all I/O activity generated by the process, including file, network, and device I/O operations.

Win32_PerfFormattedData_PerfProc_Process: Rate at which the process is reading bytes from I/O operations. This property counts all I/O activity generated by the process, including file, network, and device I/O operations.

Win32_PerfFormattedData_PerfProc_Process: Rate at which the process is issuing read I/O operations. This property counts all I/O activity generated by the process, including file, network, and device I/O operations.

Win32_PerfFormattedData_PerfProc_Process: Rate at which the process is writing bytes to I/O operations. This property counts all I/O activity generated by the process, including file, network, and device I/O operations.

Win32_PerfFormattedData_PerfProc_Process: Rate at which the process is issuing write I/O operations. This property counts all I/O activity generated by the process, including file, network, and device I/O operations.

Gets or sets the name.

Win32_PerfFormattedData_PerfProc_Process: Rate of page faults by the threads executing in this process. A page fault occurs when a thread refers to a virtual memory page that is not in its working set in main memory. This can cause the page not 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 which the page is shared.

Win32_PerfFormattedData_PerfProc_Process: Value, in bytes, that this process has used in the paging file(s). Paging files store pages of memory used by the process that are not contained in other files. Paging files are shared by all processes and lack of space in paging files can prevent other processes from allocating memory.

Win32_PerfFormattedData_PerfProc_Process: Maximum number, in bytes, that this process has used 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 lack of space in paging files can prevent other processes from allocating memory.

Percentage of elapsed time that this thread has spent executing code in privileged mode. When the operating system system service is called, the service often runs 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 and interrupts. Unlike some early operating systems, the operating system 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 the operating system on behalf of your application might appear in other subsystem processes in addition to the privileged time in your process.

Percentage of elapsed time that all of the threads of this process used the processor to execute 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 is included in this count.

Percentage of elapsed time that this process's threads have 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 operating system executive, kernel, and device drivers. The operating system 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 the operating system on behalf of your application might appear in other subsystem processes in addition to the privileged time in your process.

Win32_PerfFormattedData_PerfProc_Process: Value, in bytes, in the nonpaged pool, an area of system memory (physical memory used by the operating system) for objects that cannot be written to disk, but must remain in physical memory as long as they are allocated. The PoolNonpagedBytes in Win32_PerfFormattedData_PerfOS_Memory is calculated differently than the PoolPagedBytes property in Win32_PerfFormattedData_PerfProc_Process, so it might not equal the total of PoolPagedBytes for all instances of Win32_PerfFormattedData_PerfProc_Process. This property displays the last observed value only; it is not an average.

Win32_PerfFormattedData_PerfProc_Process: Value, in bytes, in the paged pool, an area of system memory (physical memory used by the operating system) for objects that can be written to disk when they are not being used. The PoolNonpagedBytes property in Win32_PerfFormattedData_PerfOS_Memory is calculated differently than the PoolPagedBytes property in Win32_PerfFormattedData_PerfProc_Process, so it might not equal the total of PoolPagedBytes for all instances of Win32_PerfFormattedData_PerfProc_Process. This property displays the last observed value only; it is not an average.

Gets or sets the priority base.

Win32_PerfFormattedData_PerfProc_Process: Current value, in bytes, that this process has allocated that cannot be shared with other processes.

Win32_PerfFormattedData_PerfProc_Process: Number of threads currently active in this process. An instruction is the basic unit of execution in a processor, and a thread is the object that executes instructions. Every running process has at least one thread.

Object-defined timestamp, defined by the provider.

Win32_PerfRawData_PerfProc_Process: Timestamp_Sys100NS: Timestamp value in 100 nanosecond units.

Win32_PerfFormattedData_PerfProc_Process: Current size, in bytes, of the virtual address space that 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, by using too much, the process can limit its ability to load libraries.

Win32_PerfFormattedData_PerfProc_Process: Maximum number, in bytes, of virtual address space that 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. Virtual space is finite and, by using too much, the process might limit its ability to load libraries.

Win32_PerfFormattedData_PerfProc_Process: Maximum number, in bytes, in 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 required, they are then soft-faulted back into the working set before they leave main memory.

Specific Working Set memory that cannot be shared with other processes.
