Fresh install on Alma 9 as per Unattended installation of a central server | Centreon Documentation.
Simple single server for everything setup. GUI seems to work, but the poller does not come up:
# systemctl restart centengine
# systemctl status centengine | nl

What do I have to put in there? Is it a feature that the installer didn’t do this?
