Configure .NET Application Idle Time

In your Introscope deployment, you install the .NET agent on each system that runs an application you want to monitor. After it is installed, the Microsoft Internet Information Service (IIS) controls the .NET agent. If an instrumented application stops experiencing user activity, IIS stops the application process. If IIS stops the application process due to inactivity, the node for the .NET agent in the Investigator becomes unavailable.
