Monitoring System-Wide Alarms

Unlike the alarms displayed on the Services dashboard which show only those alarms for a selected service, the Alarms dashboard is useful for viewing the state of all alarms across the entire vFoglight installation and allows you to take immediate action on them. It also shows the alarm count by time, so that alarm storms or outage events can be identified.

To monitor system-wide alarms:

• From the navigation panel, under Dashboards , select Alarms > Alarms .

The Alarms dashboard appears.
