Set the Threshold for vCenter Certificate Expiration Warnings
Starting with vSphere 6.0, vCenter Server monitors all certificates in the VMware Endpoint Certificate
Store (VECS) and issues an alarm when a certificate is 30 days or less from its expiration. You can
change how soon you are warned with the vpxd.cert.threshold advanced option.
Procedure
1 Log in to the vSphere Web Client.
2 Select the vCenter Server object and click Configure.
3 Click Advanced Settings and filter for threshold.
4 Change the setting of vpxd.cert.threshold to the desired value and click OK.
Managing Certificates with the vSphere Certificate
Manager Utility
The vSphere Certificate Manager utility allows you to perform most certificate management tasks
interactively from the command line. vSphere Certificate Manager prompts you for the task to perform, for
certificate locations and other information as needed, and then stops and starts services and replaces
certificates for you.
If you use vSphere Certificate Manager, you are not responsible for placing the certificates in VECS
(VMware Endpoint Certificate Store) and you are not responsible for starting and stopping services.
Before you run vSphere Certificate Manager, be sure you understand the replacement process and
procure the certificates that you want to use.
Caution vSphere Certificate Manager supports one level of revert. If you run vSphere Certificate
Manager twice and notice that you unintentionally corrupted your environment, the tool cannot revert the
first of the two runs.
Certificate Manager Utility Location
You can run the tool on the command line as follows:
Windows
C:\Program Files\VMware\vCenter Server\vmcad\certificate-manager.bat
Linux
/usr/lib/vmware-vmca/bin/certificate-manager
