Win32_PerfFormattedData_PerfProc_ProcessAddressSpace_Costly class

The Win32_PerfFormattedData_PerfProc_ProcessAddressSpace_Costly formatted data class provides pre-calculated data from performance counters that monitor memory allocation and use for a selected process.

This class does not appear in System Monitor. This class derives its raw data from the corresponding raw class Win32_PerfRawData_PerfProc_ProcessAddressSpace_Costly. The original data source is the PerfProc performance library. 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 Formatted Performance Data Provider.

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 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.
