I have several AO rules setup that send email in the event of a critical alarm. I'm wondering if there is a way to send another email if that critical alarms is acknowledged either by the system or an engineer. For example, we are alerting on the MSSQLSERVER Windows service for a change in state from running. That generates critical alarms. If that service is then started and is running, the alarm will clear. Can we send an email on the cleared or acknowledged event?
