The check_http plug-in was previously the only method to monitor certificates out-of-the-box with Checkmk. With the new plug-in Checkmk provides an extensive functionality to monitor certificates. This includes but is not limited to certificates provided by the HTTP protocol.
With the new plug-in you can monitor all certificates provided through a TCP connection to encrypt communication. This includes the monitoring of
- validity times (max and remaining)
- issuer fields
- subject fields
- encryption algorithm
- alternative names
- response times
- public key algorithm and size
- serial number
As with the reworked plugin to monitor web services, you are able to configure multiple services within a single rule.
