Hello ​@ismail 
It seem gorgone can’t start properly, can you check in the gorgoned log for any error here : /var/log/centreon-gorgone/gorgoned.log

if you don’t see any error maybe you can enable the debug mode like this, restart gorgone and try again :

to enable gorgone debug you need to change the configuration file, which depend on you os : 

on alma/centos, change /etc/sysconfig/gorgoned

on debian change /etc/default/gorgoned

at the end of the line starting with OPTIONS change the severity to debug, it should look like this : 

OPTIONS="--config=/etc/centreon-gorgone/config.yaml --logfile=/var/log/centreon-gorgone/gorgoned.log --severity=debug"

then restart gorgoned, and check the gorgone log file if any new log give a clue.

Regards,

Evan
