Win32_PerfRawData_Tcpip_TCP 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_Tcpip_TCP WMI class can be used in ActiveXperts Network Monitor to monitor your servers.


The Win32_PerfRawData_Tcpip_TCP raw data performance counter class represents raw data counters that measure the rates at which TCP Segments are sent and received by using the TCP protocol. It includes counters that monitor the number of TCP connections in each TCP connection state. This class is shown as the TCP object in System Monitor. The WMI source of its data is the high-performance Performance Counter Provider. The original data source is the Tcpip performance library. The corresponding formatted data class is Win32_PerfFormattedData_Tcpip_TCP. This class was added for Windows 2000.
