Use this Knowledge Script to monitor logical disk usage for a virtual machine. This script raises an event when the disk usage exceeds the threshold you set.
This Knowledge Script cannot monitor the logical disk usage for a virtual machine when the virtual machine’s disk is a mounted drive.
NOTE:
If the parent host of the monitored virtual machine is in maintenance mode, this Knowledge Script will not generate events.
Using this script and other VirtualCenter_Vm* scripts to monitor a large number of virtual machines at the same time might cause the jobs to fail. If the jobs fail on a regular basis, consider running the VirtualCenter_Vm* scripts on fewer virtual machines.
vSphere virtual machine
By default, this script runs every 15 minutes.
