Clearing an Alarm
In most cases, Foglight clears an alarm when the condition or conditions that triggered the alarm changes. For example, an alarm fires when the CPU usage metric for a monitored host exceeds a certain threshold. If the value of the metric drops below this threshold, Foglight clears the original alarm. If the alarm condition occurs again, the alarm reappears.
The Cleared column in the Alarm(s) list indicates whether an alarm has been cleared or not. In addition, cleared alarms appear dimmed.
To clear one or more alarms:
- Use the Alarm Filter to apply a filter on current or historical alarms.
- In the Alarm(s) list, select one or more alarms that you want to clear.
- Click Clear at the top of the table.
If you are filtering the list on current alarms, the alarms are removed from the list. If you are filtering the list on historical alarms, the alarms appear dimmed and Yes is listed in the Cleared column for them.
Alternatively, you can clear an alarm from the Alarms details dialog box. It appears dimmed in the dialog box when you have done so. If you are filtering the Alarm(s) list to show current alarms, the alarm is also removed from the list.
