You may configure checks for the general validity and if the certificate is allowed to be self-signed.

Additionally, you may check for specific values to monitor if you're looking at the correct certificate or if certain policies are fulfilled.

This check can be configured via ruleset at Checkmk Setup. This ruleset also allows to specifiy multiple connections to check per host/rule. Peaser refer to the ruleset for details.
