You can turn on VM and Application Monitoring and also set the monitoring sensitivity for your vSphere HA cluster.

This page is editable only if you have activated vSphere HA.
Note: vSphere HA might failover a non-healthy VM on a healthy host if VM monitoring is deactivated. The host could be selected because of a DRS recommendation or based on which host has the lowest available resources.

Procedure

  1. In the vSphere Client, browse to the vSphere HA cluster.
  2. Click the Configure tab.
  3. Select vSphere Availability and click Edit.
  4. Click Failures and Responses and expand VM Monitoring.
  5. Select VM Monitoring and Application Monitoring.
    These settings turn on VMware Tools heartbeats and application heartbeats, respectively.
  6. To set the heartbeat monitoring sensitivity, move the slider between Low and High or select Custom to provide custom settings.
  7. Click OK.

Results

Your monitoring settings take effect.
