I have created some service monitors in APM 4.0. I have an alert set up to email me when the monitor goes critical, but I only want to be emailed/alerted if the monitor is critical because the service has stopped. I do not want to be emailed/alerted just because the service/process is above the cpu threshold. Is there any way to filter out these alerts that are caused by high cpu usage and still receive alerts when the service actually stops?
