This article provides information about the detail of the "Certificate Status" vCenter alarm.
Symptoms: You may see that the "Certificate Status" vCenter alarm is triggered on vSphere Client in your VMware Cloud on AWS SDDC.
Cause
This alarm will be triggered if the "data-encipherment" certificate in vCenter has been expired.
Resolution
VMware is actively working on suppressing vCenter alarms for the entire VMware Cloud on AWS SDDCs and the actual issue of the alarms being generated for this cert expiry would be handled in the future release.
Workaround: You can ignore and clear this vCenter alarm by clicking "Acknowledge" or "Reset To Green".
Additional Information
Impact/Risks: The "data-encipherment" certificate is commonly used for the guest OS customization, however, this certificate is only used for the internal data security management in VMware Cloud on AWS SDDC. So, it does not impact your guest OS customization and there is no action required.
