Creating a Snapshot Alarm

Creating a Snapshot Alarm

An alarm can be created to display a warning or alert on a virtual machine if a snapshot grows to be larger than a threshold set in an alarm trigger.

To create a VM snapshot alarm for all virtual machines in a vCenter’s inventory select the vCenter Server. In the Manage tab select Alarm Definitions and click Add to start the Alarm Definition wizard. Give the alarm and name and description.

Add a new Trigger and select VM Snapshot Size for the Trigger.

Set the Warning Condition to the snapshot size in GB that should trigger a warning, in this example the size is set to 10 GB. Set the Critical Condition to the snapshot size in GB that should trigger a critical alert, in this example the size is set to 15 GB.

An action can be configure to send an email to an administrator if a warning or critical alarm is triggered.

The new VM Snapshot Size alarm is added to the alarm definitions.

If a snapshot grows to a size larger than what has been configured the alarm is triggered and the warning or alert is displayed on the VM and in the Alarms box in the Web Client.
