An administrator creates a custom alert in VCF Operations with CPU utilization greater than 99...

The required prerequisite is that VMware Tools must be installed and running in the target virtual machine. In VCF Operations, a recommendation can be associated with a remediation action, and supported actions can be triggered from alert recommendations when automation is configured. However, guest-level operations depend on VMware Tools because VCF Operations must communicate cleanly with the guest operating system through vCenter. The official action documentation for Reboot Guest OS for VM states that the action checks whether VMware Tools is installed on the target virtual machine, because VMware Tools is required. If VMware Tools is not installed or is installed but not running, the reboot action does not run and the job is reported as failed in Recent Tasks . The Power Off Allowed flag applies to certain reconfiguration actions, such as changing CPU or memory when the VM may need to be powered off; it is not the control for guest OS reboot . Payload templates are for outbound notifications, and VM compatibility is unrelated.
