A Central Management license allows you to display alarms generated on any managed appliance in the Alarms tab. In the example below, the grouping selected is Scope, and the level is County1. The alarm count shows as 545 alarms; 254 alarms on network devices; and 291 alarms on unknown devices. The total alarms is displayed in the upper right corner and shows 690 alarms.
If displaying alarms on an appliance level or a network level, only the alarms generated by that appliance or network level are shown.
