I'm trying to find a way to monitor active/passive/failed TCPv4 connections. The monitored host is Server 2008R2 and I'm able to get the results I need from perfmon using the following counters:

TCPv4 > Connections Active

The netstat plugin didn't seem to work for me, and I couldn't figure out the correct arguments with TCP_Check to retreive the values I need either. Can anyone point me in the right direction on this one?

Thanks!

The WMI class "Win32_PerfRawData_Tcpip_TCPv4" would be a way to return this data from Windows server 2008.

here's a powershell query on the localhost:

from Nagios, using WMIC, the equivalent query against Windows Server:
