This is good, but the customers will fire directly the next question: How should I monitor the filesystem of the database now?

I think @rjmateus should be the one who can help you with this answer.

This can only happen if the customer has changed the parameter in the rhn.conf.
To have this troubleshoting we should have a link to the documentation on how the database is monitored now. We need to turn on the check at the login page for database disk space with SQL, and state that the database check was moved to a different approach (as soon as we have it in place).
For when that would be implemented, we would need @admd
The card with the discussion is in here: https://github.com/SUSE/spacewalk/issues/28795
