Après toute cette tambouille maison, ça roule un peu mieux, ne pas oublier de configurer :
– /etc/send_nsca.cfg
1 2 3 4 | identity = "some-textual-identity" password = "leave-me-alone" server = "Server IP" port = 5668 |
– Ouvrir le port 5668 sur le serveur
– Sur le serveur, /etc/nsca-ng/nsca-ng.local.cfg
1 2 3 4 5 6 7 8 9 10 11 12 13 | listen = "*:5668" user = "nagios" command_file= "/var/lib/icinga/rw/icinga.cmd" authorize "some-textual-identity" { password = "leave-me-alone" hosts = "hostnames in icinga" # services = ".*" commands = { "PROCESS_HOST_CHECK_RESULT;.+" , "PROCESS_SERVICE_CHECK_RESULT;.+" } } |
C’est un pense-bête grossier, pas vraiment prévu pour le World Wide Web, mais c’est tellement mal documenté, que certains pourrait bien tomber ici.
