Hi, We have a Centreon 20.04.3 working like a charm for several months and years.But, since about 10 days, we can no more update and apply changes in monitoring.More precisely, when :creating a new service for an existing host, and exporting to all servers, conf is OK but monitoring is not refreshed/applied, modifying an existing service, with just a change (IP, ...), and exporting : same thing. Conf OK but monitoring is not updated.Of course, central, sat, etc… have been rebooted… No changes.We are not able to know what action we have done, which could create our problem. We have deleted 10 or 15 days from now, one host, but not attached services. So we have now services we cannot update/view because of lack of their host. But not sure that is connected to our problem.We do not know where to investigate… Any idea ? PS : Our Centreon is clustered : one Mysql server, one central, and 6 sat.

Hi,I tried today to setup a new centreon central server using the latest Rocky Linux 8.6 as the host, since i was under the assumption that RL was the standard followup to centos, and i found reference to it in the unattended script.I found it perfectly working (only had a simple issue regarding permissions in /etc/centreon-engine and /etc/centreon-broker), but i still have one issue that i cannot find a solution for, i cannot reload configuration of restart centengine from the webui. If i generate and move configuration files, then restart manually centengine, all is good and monitoring works fine. But trying to reload or restart from webui result in this log in gorgoned.log2022-07-08 18:17:49 - INFO - [legacycmd] Handling command 'ENGINERELOAD', Target: '1'2022-07-08 18:17:49 - ERROR - [action] validate plugins - unsupported operating system2022-07-08 18:20:00 - INFO - [cron] Launching job 'broker_stats'2022-07-08 18:20:00 - INFO - [cron] Launching job 'engine_stats'2022-07-08 18:20:
