The Virtual Machine Monitoring feature uses the heartbeat information that VMware Tools captures as a proxy for guest operating system availability. This feature allows vSphere HA to reset or restart individual virtual machines that have lost their ability to send a heartbeat.

The VM Monitoring page appears only if you enabled vSphere HA.
