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:
[centreon-engine@XXXXXXXX ~]$ /usr/lib/centreon/plugins//centreon_linux_ssh.pl --plugin=os::linux::local::plugin --mode=connections --hostname='XX.XXX.X.X' --ssh-backend='libssh' --ssh-username='ro_ssh_centreon' --ssh-port='22' --ssh-priv-key=/var/lib/centreon-engine/.ssh/id_ed25519 --warning='' --critical=''
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;
From the Host (ssh service):
root@XXXXXXXXX ~ systemctl status sshd
