Question:
Recently we have configured windows applications with Wily. Earlier it worked well. However, now we are seeing an issue. Each day in the afternoon, our applications going to an inactive state. (It is showing empty graphs) Then when the day starts, one by one applications return to an active state. 

Couple of times we have restarted the wily agent, but issue continues.
Answer:
Since you are using the .NET Agent, that relies on Microsoft IIS to stay alive. As long as the IIS application is being exercised (used), then the .NET Agent metrics will be transmitted to the Investigator. Once the IIS application that is being monitored has stopped being used, the IIS process itself goes away causing the .NET Agent to stop reporting metrics, gray out and eventually disappear. 

There are ways to keep IIS processes from stopping after the application has stopped being used.
