Win32_PerfFormattedData_PerfProc_JobObjectDetails class
The Win32_PerfFormattedData_PerfProc_JobObjectDetails formatted data class provides precalculated data from performance counters that monitor active processes that make up a job object.
This class represents the Job Object Details object in System Monitor and returns the same data you see in System Monitor. The original data source is the PerfProc performance library. This class derives its raw data from the corresponding raw class Win32_PerfRawData_PerfProc_JobObjectDetails. Data is provided dynamically for this class from the performance library object by the WmiPerfInst provider.
Windows Server 2003 and Windows XP: WMI data for this class is supplied by the Formatted Performance Data Provider.
The following syntax is simplified from MOF code and shows all inherited properties, including the Frequency and Timestamp properties required for class display in System Monitor. For more information about required property qualifiers, see Property Qualifiers for Performance Counter Classes. For more information about CounterType values, see WMI Performance Counter Types.

Name
Data type: string
Access type: Read-only
Label by which the statistic or metric is known. When sub-classed, the property can be overridden to be a key property. This property is inherited from CIM_StatisticalInformation.
PageFaultsPerSec
Data type: uint32
Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_COUNTER") , Counter ("PageFaultsPerSec") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
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.
PageFileBytes
Data type: uint64
Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_LARGE_RAWCOUNT") , Counter ("PageFileBytes") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
Current number, in bytes, 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.
For more information about using uint64 values in scripts, see Scripting in WMI.
PageFileBytesPeak
Data type: uint64
Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_LARGE_RAWCOUNT") , Counter ("PageFileBytesPeak") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
Maximum number, in bytes, 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.
For more information about using uint64 values in scripts, see Scripting in WMI.
PercentPrivilegedTime
Data type: uint64
Access type: Read-only
Qualifiers: CookingType ("PERF_100NSEC_TIMER") , Counter ("PercentPrivilegedTime") , PerfTimeStamp ("TimeStamp_Sys100NS") , PerfTimeFreq ("Frequency_Sys100NS")
Percentage of elapsed time that this thread has spent executing code in privileged mode. When an operating system service is called, the service often runs in privileged mode to gain access to system-private data. Such data is protected from being accessed by threads executing in user mode. Calls to the system can be explicit or implicit such as page faults and interrupts. 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.
For more information about using uint64 values in scripts, see Scripting in WMI.
PercentProcessorTime
Data type: uint64
Access type: Read-only
Qualifiers: CookingType ("PERF_100NSEC_TIMER") , Counter ("PercentProcessorTime") , PerfTimeStamp ("TimeStamp_Sys100NS") , PerfTimeFreq ("Frequency_Sys100NS")
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.
For more information about using uint64 values in scripts, see Scripting in WMI.
PercentUserTime
Data type: uint64
Access type: Read-only
Qualifiers: CookingType ("PERF_100NSEC_TIMER") , Counter ("PercentUserTime") , PerfTimeStamp ("TimeStamp_Sys100NS") , PerfTimeFreq ("Frequency_Sys100NS")
Percentage of elapsed time that the threads of this process 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.
For more information about using uint64 values in scripts, see Scripting in WMI.
PoolNonpagedBytes
Data type: uint32
Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_RAWCOUNT") , Counter ("PoolNonpagedBytes") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
Number, 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 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.

Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_RAWCOUNT") , Counter ("PoolPagedBytes") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
Number, 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.
PriorityBase
Data type: uint32
Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_RAWCOUNT") , Counter ("PriorityBase") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
Current base priority of this process. Threads within a process can raise and lower their own base priority relative to the process base priority of the process.
PrivateBytes
Data type: uint64
Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_LARGE_RAWCOUNT") , Counter ("PrivateBytes") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")

Qualifiers: CookingType ("PERF_COUNTER_RAWCOUNT") , Counter ("ThreadCount") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
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.
Timestamp_Object
Data type: uint64
Access type: Read-only
Object-defined timestamp, defined by the provider. This property is inherited from Win32_Perf.
For more information about using uint64 values in scripts, see Scripting in WMI.

Data type: uint64
Access type: Read-only
High performance counter timestamp. A value could be obtained by calling the Windows function QueryPerformanceCounter. This property is inherited from Win32_Perf.
For more information about using uint64 values in scripts, see Scripting in WMI.
Timestamp_Sys100NS
Data type: uint64
Access type: Read-only
Timestamp value in 100 nanosecond units. This property is inherited from Win32_Perf.
For more information about using uint64 values in scripts, see Scripting in WMI.
VirtualBytes
Data type: uint64
Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_RAWCOUNT") , Counter ("VirtualBytes") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
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, by using too much, the process can limit its ability to load libraries.
For more information about using uint64 values in scripts, see Scripting in WMI.
VirtualBytesPeak
Data type: uint64
Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_LARGE_RAWCOUNT") , Counter ("VirtualBytesPeak") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
Maximum number, 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. Virtual space is finite and, by using too much, the process might limit its ability to load libraries.
For more information about using uint64 values in scripts, see Scripting in WMI.
WorkingSet
Data type: uint64
Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_LARGE_RAWCOUNT") , Counter ("WorkingSet") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
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.

Access type: Read-only
Qualifiers: CookingType ("PERF_COUNTER_LARGE_RAWCOUNT") , Counter ("WorkingSetPeak") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")
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.
