In CA APM is it possible to implement the alerts notification in below pattern.
Alert at first occurrence and repeat alert after Nth occurrence.
Look at the workstation guide concerning Action Delays.
To answer your query, We don't have occurrence criteria for alerts but we do have time delays.
Also to suggest something, what I believe is that time delay is more effective or impactful for successful monitoring rather than the no. of occurrences delay. (until some special requirement is there)
Because say we have bulk of alert mails been triggering frequently, we would be notified falsely (or say redundantly ) for same issue in case of n-th occurrence setting. But if we have Time Delays, it would make more sense.
Also say if two alerts are triggering with 12 hours time gap, in case of n-th occurrence we would not be notified with positive alert. But same is not with time delay mechanism.
Thought to share my understanding with you. Hope it makes sense.
