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

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


Launch the vSphere Client and log in to a vCenter Server system.


  1. (Optional) Select VM Monitoring Only to restart individual virtual machines if their heartbeats are not received within a set time. You can select VM and Application Monitoring if you also want to enable application monitoring.
  2. Set the virtual machine monitoring sensitivity by moving the slider between Low and High. Select Custom to provide custom settings.
  3. Click Next.
