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 Client.
  2. Select the vCenter Server object and click Configure.
  3. Click Advanced Settings.
  4. Click Edit Settings and filter for threshold.
  5. Change the setting of vpxd.cert.threshold to the desired value and click Save.
