Use this Knowledge Script to monitor virtual machine snapshots. This script raises an event when the number of all snapshots, the size of all snapshots, or the age of a snapshot or a reverted snapshot exceed the thresholds you set. This script generates data streams for the number of all snapshots, the size of all snapshots, and the age of a snapshot or a reverted snapshot.
NOTE:This script will not generate events for virtual machines that have a parent host in maintenance mode.
