I assumed that I followed this tutorial : Linux SSH | Centreon Documentation

• created a ro_ssh_centreon on the hosts that I whant to monitor
• used the centreon-engine user on centreon server
• created the ssh key and then copy the key to the host that I whant to monitor and then get a ssh connexion to , but needed the ro_ssh_centreon user password 

So , now I’m not sure if it’s working or not when I try using os-linux-ssh-connection-custom .

From centreon with the perl script:


OK: Total connections: 4 | 'total'=4;;;0; 'con_established'=4;;;0; 'con_synSent'=0;;;0; 'con_synReceived'=0;;;0; 'con_closed'=0;;;0; 'con_timeWait'=0;;;0; 'con_listen'=12;;;0; 'con_finWait2'=0;;;0; 'con_finWait1'=0;;;0; 'con_closing'=0;;;0; 'con_closeWait'=0;;;0; 'con_lastAck'=0;;;0;
