vSphere HA can be configured to monitor virtual machines, so that unresponsive VMs can be restarted (reset). This is achieved by enabling VM monitoring on the HA cluster.
You can also enable application monitoring. This will restart a VM if the VMware Tools application heartbeats are not received within a predefined timeout value.
The following procedure describes how to configure VM monitoring on an HA cluster:
From the vCenter's Home inventory, navigate to the Hosts and Clusters view.
Select the cluster and navigate to Manage | Settings | vSphere HA, and click on Edit.
In the Edit Cluster Settings window, click on VM Monitoring to expand and view its additional settings.
To enable VM monitoring, you can choose between the Disabled, VM Monitoring only, and VM and Application Monitoring options.
With the monitoring type selected, set a planned Monitoring Sensitivity value, and click on OK as shown in the following screenshot:
