[Nagiosplug-help] erreur log

[Guyard Marc]

Bonjour la liste,

J'ai un probleme de log. Plusieurs de mes check me donne l'erreur 
suivante alors que tout est en vert sauf la colone host qui est en 
rouge. Dans les logs j'ai l'erreur suivante :

Name or service not known


et l'erreur :

check_dns: Unknown argument - (null)

alors que tout est correct dans me configuration

checkcommand :
# 'check_dns' command definition
define command{
        command_name    check_dns
        command_line    $USER1$/check_dns -H www.yahoo.com -s $ARG1$
        }

services :
define service{
        use                             generic-service         ; Name of service template to use
        host_name                       SERVICE_CHECK_DNS
        service_description             Verification des DNS
        is_volatile                     0
        check_period                    24x7
        max_check_attempts              3
        normal_check_interval           3
        retry_check_interval            1
        contact_groups                  admin_X
        notification_interval           120
        notification_period             24x7
        notification_options            w,u,c,r
        check_command                   check_dns!IP
        }

mon hosts et hostgroup existe bien.

Quelqu'un a une idée pour resoudre ce probleme?

Merci
