Description:
We currently have no way of knowing the state of an event over time (unless it's based on
graphed values). This has been requested in the past (see bug 33826) and should not be
difficult to add.
How to repeat:
Have an alarm go to warning, then to success, then to critical.
You have no insight into how this event behaved over time other than the last time it
reached it's worst state and what it's currently at.
Suggested fix:
Add a tab to the event popup called "history" and display the state changes in a
scrollable box. We may want to clip this if there are too many state changes for that
event.
Also, the popup doesn't show the current state. It's trivial to add that in for
completeness.
I'll likely need to work with Sloan or Oldag to get the history surfaced to the UI layer.
On the other hand, I'm fairly sure we already store this info in an easily consumable
format so it should not be difficult.
