Win32_PerfRawData_TapiSrv_Telephony vbscript sample code

The foundations for Manageability in Windows is Windows Management Instrumentation (WMI; formerly WBEM) and WMI extensions for Windows Driver Model (WDM).

ActiveXperts Network Monitor provides the ability to build monitor check routines based on WMI. ActiveXperts has collected more than a hundred WMI samples. You can use these samples as a base for new check routines you can write yourself. The Win32_PerfRawData_TapiSrv_Telephony WMI class can be used in ActiveXperts Network Monitor to monitor your servers.


The Win32_PerfRawData_TapiSrv_Telephony raw data performance counter class represents the raw performance data for the telephony system. This class is shown as the Telephony object in System Monitor. The WMI source of its data is the high-performance Performance Counter Provider. The original data source is the TapiSrv performance library. The corresponding formatted data class is Win32_PerfFormattedData_TapiSrv_Telephony. This class was added for Windows 2000.
