It would be great to have an option to display history graphs for elements that are in the alarm state.
For example, when a processor goes above 90% a small history graph is displayed. The administrator would see what it was like before the alarm and how long it has been in alarm.
Perhaps the history graph would be able to have a color indication where the alarm was triggered.
I would use this with things like High Percent Utilization of interfaces, CPU Load, Disk space, Errors, etc.
