Alarm Limits
To configure alarm action limits on an alarm (in the Actions tab of the Alarm Configuration window), right-click on an alarm history record and select Alarm Limits to open the Alarm Tracking Information window. This window displays the configured action limit, the number of times the action has been taken (Total Count), the number of times the action has been taken since the last reset, and the time of the next reset. You can also manually reset the alarm limit count using the Reset Count button. This resets the count for only this alarm on only this device or interface.
Alarm History Options
Change certain alarm history parameters in the Alarm History section of the Alarm options (Administration > Options > Alarm).
- By default, the alarm history is maintained for 14 days. You can change the number of days in the options.
- By default, a history record is created the first time an alarm is raised on a device or interface, and also when it is cleared. Select Enable Detailed Alarm History in Administration > Options > Alarm so that repeat occurrences of an alarm being raised are also recorded.
- You can enable an option to preserve alarm triggering events, so that any triggering events are stored with the alarm history record. If a triggering event is stored with the currently selected history record, you can view the event by selecting the View Trigger button in the Alarm History window. If there is no triggering event, the button is disabled.
