Nagios doesn't alert on a CRITICAL return from check_sn


Good afternoon,

Nagios 2.12
Plugins 1.4.11
OS: CentOS 5

I am using the check_snmp command as follows:

/usr/lib/nagios/plugins/check_snmp -H host1 -C deleted -o .,.,. -w :3,:2,:1 -c :5,:5,:3 -l load

‘snmp_load’ command definition

define command{
command_name snmp_load
command_line /usr/lib/nagios/plugins/check_snmp -H $HOSTADDRESS$ -C $ARG1$ -o .,.,. -w :$ARG2$,:$ARG3$,:$ARG4$ -c :$ARG5$,:$ARG6$,:$ARG7$ -l load

define service{
use generic-service

     hostgroup_name         servers
     service_description    SNMPLOAD
     contact_groups         servers
     notification_options   u,c,r
    check_command snmp_load!deleted!3,2,1!6,5,3


The plugin, when run from the command line, returns:

load CRITICAL - 7 6 5 | iso. iso. iso.

The return status from the plugin is ‘2’, which should be interpreted as CRITICAL.

But the GUI shows the service in a WARNING state, not critical, and no email notification goes out.

SNMPLOAD WARNING 2008-09-19T15:53:13 0d 2h 4m 53s 5/5 load WARNING - 4 6 6

It is almost as if the service is calling a different snmp_load command, but if I modify the one in commands.cfg, the behavior does change.

Any ideas on this would be most helpful.
