For the Current Alarms and Historical Alarms section in the Alarms Report:
- Current Alarms: Shows alarms that are still active and have not been cleared; they are "time range insensitive" and displayed regardless of the selected time frame. The same behavior can be seen when using the "Current" alarms filter in the Alarms dashboard.
- Historical Alarms: Shows alarms that have been created, cleared, or acknowledged within the supplied time range. The same behavior can be seen when using the "Historical" alarms filter in the alarms dashboard.
For historical alarms, the Cleared Time and Ack'ed Time of the alarms can be viewed from the Alarms dashboard; for example, to verify acknowledged alarms during a specific time range:
- From the left navigation panel go to Alarms Management > Alarms.
- Enable the Cleared Time and Ack'ed Time columns.
- Set the Alarm Filter to Historical (Alarms that have been created, cleared, or acknowledged within the supplied time range).
- Specify the desired time range.
- Review the Time (Created Time) and Ack'ed Time columns.
