Win32_PerfRawData_PerfProc_ThreadDetails_Costly class

The Win32_PerfRawData_PerfProc_ThreadDetails_Costly raw performance data class provides raw data from performance counters that monitor aspects of thread behavior that are difficult to collect. These counters are distinguished from those in the Win32_PerfRawData_PerfProc_Thread object by their high overhead. The suffix "Costly" indicates that obtaining data from the counters contained in this class uses system or network resources heavily and can affect performance.

The data in instances of this class are not displayed in System Monitor. The original data source is the PerfProc performance library. The corresponding formatted data class is Win32_PerfFormattedData_PerfProc_ThreadDetails_Costly. Data is dynamically provided 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 Performance Counter 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.

• Properties

Properties

The Win32_PerfRawData_PerfProc_ThreadDetails_Costly class has these properties.

Caption

Data type: string

Access type: Read-only

Short textual description for the statistic or metric. This property is inherited from CIM_StatisticalInformation.

Description

Data type: string

Access type: Read-only

Textual description of the statistic or metric. This property is inherited from CIM_StatisticalInformation.

Frequency_Object

Data type: uint64

Access type: Read-only

Frequency, in ticks per second, of Timestamp_Object. This property is defined by the provider. This property is inherited from Win32_Perf.

For more information about using uint64 values in scripts, see Scripting in WMI.

Frequency_PerfTime

Data type: uint64

Access type: Read-only

Frequency, in ticks per second, of Timestamp_Perftime. 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.

Frequency_Sys100NS

Data type: uint64

Access type: Read-only

Frequency, in ticks per second, of Timestamp_Sys100NS (10000000). This property is inherited from Win32_Perf.

For more information about using uint64 values in scripts, see Scripting in WMI.

Name

Data type: string

Access type: Read-only

Qualifiers: Key, MaxLen (256)

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.

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.

Timestamp_PerfTime

Data type: uint64

Access type: Read-only

High Performance counter timestamp. A value can 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.

UserPC

Data type: uint64

Access type: Read-only

Qualifiers: DisplayName ("User PC") , PerfDefault, CounterType (256) , DefaultScale (0) , PerfDetail (400)

Current User Program Counter for this thread.

For more information about using uint64 values in scripts, see Scripting in WMI.

Remarks

All classes derived from Win32_Perf are designed to be used with a refresher object. For more information about how to create and use a refresher object in C++, see Accessing Performance Data in C++. For more information about how to create and use a refresher object using scripts, see Refreshing WMI Data in Scripts.

The performance class and property qualifiers determine how to interpret the class data. For more information, see Class Qualifiers for Performance Counter Classes and Property Qualifiers for Performance Counter Classes.
