The Application Processes Layer
The Application Processes layer of an IIS web server periodically checks whether the critical web server processes are running or not, and also reports the percentage of CPU and memory resources utilized by these processes. In addition, the layer also monitors the eventlogs on the IIS web server host from time to time, so that critical application and system-related errors are instantly detected.
