We upgraded to the Dx NetOps to version 22.2.7, after alarm console time range is showing locked.
And the option to use it is greyed out.
..
Dx NetOps Portal
Release : 22.2.3 +
Release : 23.3.x
Before 21.2.3, you could select a custom time range for alarms in the PC Alarm Console
This was changed in 21.2.3 to provide a live alarms view.
All live alarms will be shown, and the ability to view a custom time range is deprecated.
This is Functioning As Designed (FAD)
