NetCrunch provides a predefined dedicated monitoring pack for Microsoft IIS:
Tools->Monitoring Packs & Policies->Monitoring Packs->Microsoft->IIS.
You can check the list of predefined alerts and reports, add nodes and modify rules of this pack in the Monitoring Pack Settings window.
IIS Server with NetCrunch can be monitored in several ways:
Setting up an alert for the HTTP network service
It must be added to the monitored list for the node with running IIS. Then you can setup an alert for this network service, e.g. when its state changes to DOWN or UP, it is responding slowly and/or too many packets are lost. To do this select either the Network Service State Event, Network Interface State Rule or the Event Trigger for Network Service Counter class during event definition.
Setting up an alert for a Windows service related to this Web server
During actual event definition, select the Windows Service State Event class and select such Windows service as IIS Admin Service. You can choose to generate an alert if this service is stopped, paused or run for any reason so that notification or another type of preventive action is taken.
Setting up an alert using the Event Trigger for Windows Performance Counter class
This class is available on the Windows tab of the Add Monitoring Event window. Any number of counter objects related to IIS can be setup (i.e. actual specific counters for each need to be chosen).
