I have set up monitoring on an web application. All of the components show Healthy State no matter what. We can shutdown some of the servers, stop the WWW Publishing service or other services and it still shows Healthy. I've checked the Event logs, restarted IIS when instructed.
The only thing I can see as a possible issue is when I look at the State View for the application there is nothing in the APM ASP .NET Web Service Application Component column and nothing in the APM Windows Service Component column. In other words they show as not monitored. All of the other columns have green check marks.
