Dashboards provide visibility into critical aspects of your cluster, including Storage Virtual Machine (SVM, formerly known as Vserver) health, system and cluster performance, and storage space utilization. You can also configure alarm thresholds and view information about alarms.
For example, you can modify the warning and critical alarm thresholds for space used on aggregates. You might set the warning threshold to 50% and the critical threshold to 60%. The cluster generates an "over threshold" alarm when the value exceeds the configured threshold. In addition, the Event Management System (EMS) generates a message when an alarm is generated or cleared, if you configured it to do so.
