An administrator has noticed an increasing number of inactive VMS being left powered on within...

The administrator should assign the VMs to an Inactive:VM category as an action and trigger a playbook on alert with the Inactive VM alert policy. By doing this, they can create a custom category to group and identify the inactive VMs and use a custom alert policy to trigger a playbook that can perform automated actions on them, such as powering them off, deleting them, or sending notifications. This is based on the general practices in managing VMs in a multicloud environment, as well as the specific features and requirements of Nutanix X-Play and Nutanix Calm. References:
