You can configure the Carbon Black EDR server to display a warning banner when any of its server certificates is ready to expire. The values available for this are: 0, 15, 30, 60 or 90 days. If the value provided is 0 (zero), no warning appears.
This value can also be set through the console as described here, or by providing a value in
CbServerCertWarnBeforeExpirationDays in the cb.conf file, in which case it cannot be changed in the console. For more information about cb.conf, see the VMware Carbon Black EDR Server Configuration Guide
If enabled, the warning displays for any expiring certificate listed on the Server Certificates page, even one not used by any sensor groups. If you see warnings for a certificate you are not using and will not use later, delete the certificate to prevent unneeded warnings. See Delete a Certificate from a Server.
- Click Username > Settings.
