Can you restart these services and try exporting the pollers’ configuration again?

systemctl restart cbd centengine gorgoned

Done and here is the result ,

Ok, so I understand it still does not monitor your hosts?

Can you check that engine and broker’s configuration files have been updated recently?

I can’t reproduce your issue, so I’m not sure what isn’t working exactly, but I noticed that you are not using the last release of Centreon 21.10.

Can you update you server using this procedure and then export your configuration again (with the restart method)?
