I have this scenario I'm looking for assistance on. These particular email alerts I have integrated into OpsGenie get filtered based on the subject name and assigned an Alias for the deduplication effort. That being "WARNING: server". When the server comes back up, I get a similar subject, but it states "OK: server". What I'd like to do is auto-close the alert when the OK message happens, but I want to close both the OK alert and the WARNING alert. Should I make the filter rule for the alias just on the term "server" and group both together, then close on the alias? Or should I keep the two as separate alerts and manage independently? Is there a better way of doing this I'm overlooking?
