Win32_PerfFormattedData class
The Win32_PerfFormattedData performance counter class is an abstract base class for the preinstalled, calculated data classes. An example of such a class is Win32_PerfFormattedData_PerfDisk_LogicalDisk. These classes contain calculated values provided by the high-performance Formatted Performance Data Provider.
The following syntax is simplified from MOF code and shows all of the inherited properties.

Properties
The Win32_PerfFormattedData class has these properties.
-
Caption
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: MaxLen (64)
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 the Timestamp_Object property. When sub-classed, the provider defines this property.
For more information about using uint64 values in scripts, see Scripting in WMI.
This property is inherited from Win32_Perf.
-
-
Frequency_PerfTime
-
-
Data type: uint64
-
Access type: Read-only
Frequency in ticks per second of the Frequency_PerfTime property. A value can be obtained by calling the Windows function QueryPerformanceCounter.
For more information about using uint64 values in scripts, see Scripting in WMI.
This property is inherited from Win32_Perf.
-
-
Frequency_Sys100NS
-
-
Data type: uint64
-
Access type: Read-only
Frequency in ticks per second of the Timestamp_Sys100NS property (10000000).
For more information about using uint64 values in scripts, see Scripting in WMI.
This property is inherited from Win32_Perf.
-
-
Name
-
-
Data type: string
-
Access type: Read-only
-
Qualifiers: MaxLen (256)
Label by which the statistic or metric is known. When subclassed, this 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. The provider defines his property.
For more information about using uint64 values in scripts, see Scripting in WMI.
This property is inherited from Win32_Perf.
-
-
Timestamp_PerfTime
-
-
Data type: uint64
-
Access type: Read-only
High Performance counter timestamp. A value can be obtained by calling the Windows function QueryPerformanceCounter.
For more information about using uint64 values in scripts, see Scripting in WMI.
This property is inherited from Win32_Perf.
-
-
Timestamp_Sys100NS
-
-
Data type: uint64
-
Access type: Read-only
Timestamp value in 100 nanosecond units.
For more information about using uint64 values in scripts, see Scripting in WMI.
This property is inherited from Win32_Perf.
