Hi Winkle,
You need to configure which .NET applications (IIS apps plus any others) and which IIS App Pools you wish to monitor using these 2 properties in the agent profile.
introscope.agent.dotnet.monitorApplication
introscope.agent.dotnet.monitorAppPools
Here is an example for the IIS application (w3wp.exe) and the App Pools I have for MS StockTrader sample application:
introscope.agent.dotnet.monitorApplications=w3wp.exe
introscope.agent.dotnet.monitorAppPools="StockTrader6WebAppPool","StockTrader6ConfigAppPool", "StockTrader6BslAppPool"
(If you do not set introscope.agent.dotnet.monitorAppPools the agent will monitor all .NET apps running under IIS)
Full info here: Configuring the .NET Agent - CA Application Performance Management - 10.2 - CA Technologies Documentation
Hope it helps
Regards,
Lynn
