We are sorting by Last Occurrence, but the Alarm Console in PM is not showing the most recent events when the number of events is greater than the alarm console limit.
We have the limit set to the maximum of 20000 and have more alarms than that.
Release: 22.2.5 and earlier
The fix for DE551603 is currently targeted for DX Netops Performance Management 22.2.5
Note that this is subject to change and there are no release dates that can be provided at this time.
