Hi! The big issue is that at “Reporting->Availability->Hosts” i see al hosts with “ UNDETERMINED” status for any period selected. In mariadb.log i get this error from 10 to 10 min - “[Warning] Aborted connection xxx to db: 'centreon' user: 'centreon' host: 'localhost' (Got timeout reading communication packets)”
I can log in to mysql/mariadb server with my centreon user and password stored in /etc/centreon/centron.conf.php. This is my /etc/my.cnf.d/centreon.cnf

# cat centreon.cnf
