To create an alert for idle VMs, the administrator needs to specify the following parameters:

• Scope: Select the category value Environment:Production to filter the VMs that are affected by the alert.
• Metric: Select CPU Usage (%) as the metric to monitor the VMs’ CPU utilization.
• Condition: Select Less Than as the operator and enter 5 as the threshold value to define the idle state.
• Duration: Enter 5 as the duration value and select Minutes as the unit to set the time period for the idle state.

To create a Playbook with the alert as the trigger, the administrator needs to do the following steps:

• Name: Enter a descriptive name for the Playbook, such as Idle VM Alert.
• Trigger: Select Alert as the trigger type and choose the alert that was created for idle VMs.
• Action: Select Email as the action type and enter the recipient email address, subject, and message for the notification.

The Playbook will run whenever the alert is triggered and send an email to the administrator informing them about the idle VMs.

The best way to automate the scale-out of the application layer using a third-party tool is to create a Playbook with a webhook as a trigger and a REST API call as an action. A webhook is a mechanism that allows a third-party service to send a notification to a Calm server when a certain event occurs, such as a code commit or a build completion. A REST API call is a way to interact with the Calm server programmatically, such as launching a blueprint or scaling out a service. By creating a Playbook that combines these two elements, the administrator can enable the third-party tool to trigger the scale-out action on the Calm server with a single command. The other options are either not feasible, not efficient, or not relevant for this task. References: Nutanix Calm: Playbooks - Read the Docs and Nutanix Calm: REST API - Read the Docs.
