Once the SDDC health solution collects the health of the vCenter health services, it monitors the ESXi host and vCenter root certificates, on a daily basis. It also alerts the user to avoid environment downtime. The certificate properties are published under the Certificate Summary group.

ESXi host certificate and vCenter root certificate monitoring

ESXi host certificates and vCenter root certificates are monitored, and alerts are generated based on predefined thresholds set in the global settings.

To access the global settings in VMware Aria Operations:

  1. Log in to the VMware Aria Operations user interface with administrator privileges.
  2. Click the Administration tab.
  3. In the left menu, expand the Management section and select Global Settings -> System Setting.
  4. Scroll down and select Threshold For Adapters Certificate Expiration Alert.

Alerts are raised based on the number of days set for critical, immediate, and warning category under the global setting. The ESXi host and vCenter root certificates contain the following three symptoms:

  • Critical: The certificate has expired or will expire shortly.

  • Immediate: The certificate will expire shortly.

  • Warning: The certificate is about to expire.

These symptoms are triggered if the certificate expiry date has reached the threshold condition set for critical, immediate, and warning. A notification is displayed explaining the alert information.
