we have different SSL ports on the systems and would still like to solve the SSL certificate monitoring via a rule.
For this purpose, we have maintained the custom attribute “SSLPORT” in the host, but when we try to specify it in the TCP port (using $_HOSTSSSLPORT$), we get the following message: The text $_HOSTSSSLPORT$ is not a valid integer number.
However, I can use variables in the host name / IP address without any problems (e.g. $HOSTALIAS$).
This means that the check for “number” would have to be removed from the field “TCP port” (at least if a variable is specified).
However, this also means that you can/must define not only “text” but also “numbers” for custom variables.
