You can use the default Virtual SAN alarms to monitor the cluster, hosts, and existing Virtual SAN licenses.
The default alarms are automatically triggered when the events corresponding to the alarms are activated or if one or all of the conditions specified in the alarms are met. You cannot edit the conditions or delete the default alarms. To configure alarms that are specific to your requirements, create custom alarms for Virtual SAN. SeeCreating a vCenter Server Alarm for a Virtual SAN Event.
