Hi Florian,
My target is to measure the number of current connections handled by the IIS, because the customer has noticed application delays when the number of connections is above a threshold.
Well, we've managed to extract and depict this performance counter in Introscope by editing the PerfMon configuration in IntroscopeAgent.profile, to provide the Web Service Object performance counters as shown in the Web Service Object: Internet Information Services (IIS); Core Services
By editing the following parameter in IntroscopeAgent.profile:
introscope.agent.perfmon.metric.filterPattern=|Web Service|*|*
Below is a screenshot from Introscope:
Thanks, Fotis
