Taken from an old post that was never answered.... It seems the alert engine is not aware that an application pool is unmanaged, only it's state. So how do we code an exception into our alert so we no longer get alerted for unmanaged app pools?
AppInsight for IIS: Application Pool - Status - is not equal to - Unmanaged
The actual trigger condition:
AppInsight for IIS: Application Pool - State - is equal to - Stopped
