guest supervision

Hello,
I am new to centreon. I deployed centreon 20.10 as indicated on the official documentation and activated the IT 100 license. I can't get the hosts to monitor. Could you help me on this level?

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

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?

ls -l /etc/centreon-engine /etc/centreon-broker

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)?
