Win32_PerfFormattedData_PSched_PSchedPipe class

The Win32_PerfFormattedData_PSched_PSchedPipe formatted data class provides pre-calculated data from performance counters that monitor pipe performance data from the packet scheduler.

This class represents the PSched Pipe object in System Monitor and returns the same data found in System Monitor. This class derives its raw data from the corresponding raw class Win32_PerfRawData_PSched_PSchedPipe. The original data source is the PSched 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 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.

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.
