An X-Play Trigger is a condition that initiates a Playbook. There are four types of X-Play Triggers: Alert, Audit, Event, and Time1. An Alert Trigger is based on a Prism alert, such as a VM power state change or a disk failure. An Audit Trigger is based on a Prism audit entry, such as a user login or a cluster operation. An Event Trigger is based on a Prism event, such as a VM creation or deletion. A Time Trigger is based on a schedule, such as daily, weekly, or monthly2. In this scenario, the administrator needs to create a Playbook to be notified when VMs are deleted. Therefore, the appropriate X-Play Trigger would be an Event Trigger, since VM deletion is a Prism event.

A playbook REST API action allows the administrator to send an HTTP request to a specified endpoint, such as the Prism Central API, to perform an operation, such as deleting a VM. A playbook webhook action allows the administrator to send a payload to a specified URL, such as a ServiceNow webhook, to trigger an event, such as an approval flow. Both of these actions can be used to automate the deletion of VMs from a ServiceNow approval flow, where the developers can request and confirm the removal of their environments. A playbook webhook trigger and a playbook REST API trigger are not valid options, as they are used to initiate a playbook based on an external event, not to perform an action within a playbook.

According to the Nutanix Calm Administration Guide1, the minimum system requirements for Prism Central are 32 GB of RAM and 8 vCPUs. If the production Prism Central has less than the minimum RAM, it may affect the performance of Calm and other services running on Prism Cen

When a Blueprint is launched via Marketplace, it uses the credential that is configured in the Project Environment. If the credential is invalid, the Blueprint deployment will fail with a check login error. To fix this issue, the developer needs to verify and update the credential in the Project Environment and ensure that it has the required permissions to access the target infrastructure and applications.
