If your virtualization environment has snapshots growing like weeds in the yard then you are not alone. The more snapshots that exist for longer periods of time degrades the performance of the virtual machine the snapshots are on. BlankTimelineTo further illustrate the flexibility of the automation engine in the Reflex VMC we will illustrate a real world example of addressing this problem. This example dives deeper into the concept of an Action. An Action is at minimum a script and can also include a VQL query. An action can either run a script either on a periodic basis or whenever the output of a VQL query changes. We will illustrate an Action that uses the output of a VQL query in a subsequent post. For now, we will take a look at Actions that are run on a periodic basis. First lets describe what we want to accomplish with this policy:

  1. Send an e-mail to the owner of a VM and the IT Admin when they have reached X snapshots and the image is not marked as an exception
  2. Send an e-mail to the owner, IT Admin and the Group Admin when they have reached X snapshots, the image is not marked as an exception and the X snapshot condition has lasted more than Y days
  3. To make sure virtual machines have the proper data on them, Query for all machines that have no owner set and tell the Virtualization Architect the name of the machine and what functional group the VM is in if any
