We have a number of alerts which take a long time to resolve, and during the time the alerts are open we receive a duplicate alert every 4 hours for the same issue which are deduplicated in OpsGenie. In a case recently we had an alert at warning level that had reached its x100 deduplications so when the alert changed to critical it wasn't picked up.
How do I create an escalation to a management team to alert them that an alert has been deduplicated 80 times, as this implies that we have had a problem open for many days.
I have tried an escalation policy but I am limited to raising an escalation if the alert isn't fixed within 1440 minutes of opening.
