Win32_PerfFormattedData_TermService_TerminalServices class

The Win32_PerfFormattedData_TermService_TerminalServices formatted data class provides pre-calculated data from performance counters that monitor Terminal Services summary data.

This class is shown as the Terminal Services object in System Monitor. The WMI source of its data is the high-performance Formatted Performance Data Provider. This class derives its raw data from the corresponding raw class Win32_PerfRawData_TermService_TerminalServices. The original data source is the TermService 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.

• Properties

Properties

The Win32_PerfFormattedData_TermService_TerminalServices class has these properties.

ActiveSessions

Data type: uint32

Access type: Read-only

Qualifiers: CookingType ("PERF_COUNTER_RAWCOUNT") , Counter ("ActiveSessions") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")

Number of active Terminal Services sessions.

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.

InactiveSessions

Data type: uint32

Access type: Read-only

Qualifiers: CookingType ("PERF_COUNTER_RAWCOUNT") , Counter ("InactiveSessions") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")

Number of inactive Terminal Services sessions.

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 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.

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.

TotalSessions

Data type: uint32

Access type: Read-only

Qualifiers: CookingType ("PERF_COUNTER_RAWCOUNT") , Counter ("TotalSessions") , PerfTimeStamp ("Timestamp_PerfTime") , PerfTimeFreq ("Frequency_PerfTime")

Total number of Terminal Services sessions.

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.
