Looking at the events tab of a threshold profile if I choose 1hr or 4hr or any timeframe the results are always identical, 1 - 100 of 101 events. Spectrum shows the alarms count raised by this specific threshold is over 2k alarms in the last few days.
Release : 21.2
Component : CA Performance Center
Workaround:
Select 50 rows and then swap back to 100 rows.
Fixed in 21.2.8
