The volume capacity monitoring feature can send alert messages when dynamic volumes reach certain size thresholds. In addition, with the use of a script, volume capacity monitoring can automatically grow a volume when it reaches a specified capacity. With a script, you can conserve disk space on your servers because space is distributed automatically on an as-needed basis. You do not have to manually allocate the additional disk space when it is required.

The following steps set up a rule for growing a volume when a Capacity Monitoring threshold error occurs. The volume capacity monitoring feature monitors the capacity of the volume on your system; it has two thresholds - a Warning threshold with a default setting of 80% of capacity and a Critical threshold with a default setting of 90% of capacity. These are the points at which the volume capacity monitoring feature sends an alert. To automate volume growth, you can associate an executable file, volgrow.cmd, with a Rule Manager rule so that when the Critical threshold is passed, a command to expand the volume is automatically sent.

Before setting up a new rule to execute a command, you must enable the VEA service and the GridNode service to interact with the desktop. These steps are not required if the new rule sends only email notifications.
