This monitor tracks the vCenter Alarm 'Host flash capacity exceeds the licensed limit for Virtual SAN'.
By default, the alarm is triggered by the following event:
|▪||com.vmware.license.vsan.HostSsdOverUsageEvent: Current capacity of SSD disks on the host exceeded the Virtual SAN license capacity, or evaluation period of Virtual SAN license expired.|
Check virtual SAN configuration. You can decrease capacity by removing unnecessary data disks.
