Hello,
we have several Redhat 9 systems (but the problem also exists on older Redhats), where the postfix status is displayed as critical and not running. This is basically correct, but the postfix systemd service is intentionally set to disabled.
Does checkmk ignore this disabled/enabled systemd setting? How can we leave the postfix package installed on the server and stop/disable the service without checkmk reporting this?
The only thing I can think of now is to deactivate the postfix service in checkmk on the relevant systems!
As far as I know the Postfix check is built into the agent itself and not a separate plugin. Therefore you cannot turn it on & off via rules as you can with other plugin-based checks such as the one for Redis, for example.
What I’d do is simply disable the service for the hosts. I’d probably do it by manually creating a rule for “Disabled services” matching all the host names instead of going through each host’s service discovery & kicking them out, but you can go either way.
