Win32_PerfRawData_MSDTC_DistributedTransactionCoordinator class

The Win32_PerfRawData_MSDTC_DistributedTransactionCoordinator raw performance data class provides raw data from performance counters that monitor the Microsoft Distributed Transaction Coordinator.

This class represents the Distributed Transaction Coordinator object in System Monitor. The WMI source of its data is the high-performance Performance Counter Provider. The original data source is the MSDTC performance library. The corresponding "cooked" or calculated data class is Win32_PerfFormattedData_MSDTC_DistributedTransactionCoordinator. Instances of this class contain raw data. You can programmatically calculate the same data displayed in the Performance utility under Administrative Tools in the Start Menu or in the System Monitor window of the Perfmon utility. For more information about how to calculate the displayable data or CounterType values, see WMI Performance Counter Types. 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 Raw Performance Counter Classes.

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.
