Hi Max,
Have you tried running it as the Nagios user i.e. with the same privileges as Nagios?
cheers, Tim

Hi,

Is anyone using the check_snmp_cisco_memutil script? I got this off of NagiosExchange and haven't been successful at getting it to function properly. I'm running Nagios 1.2 and I have the appropriate Net::SNMP and other Perl packages installed, because I'm doing a ton of other checks across SNMP. I can run the command from the command line successfully such as:

./check_snmp_cisco_memutil -H myhost -C mycommunity -w 60 -c 65
Status is OK - MEMORY: total: 67.11 MB, used: 27.50 MB (41%), free: 39.61 MB

I have defined a command in my checkcommands.cfg as:


define command{
        command_name    snmp_mem
command_line $USER1$/check_snmp_cisco_memutil -H $HOSTADDRESS$ -C mycommunity -w 60 -c 65
        }

Also, I've defined the service in services.cfg:

define service{
        use                             basic-service
        name                            snmp-mem
        service_description             MEM
        check_command                   snmp_mem
        host_name            myhost
        }

Basically, the service MEM I have defined shows up under the host specified, but the plugin fails saying there is no output. I've configured quite a few services in the instance of Nagios I have up and running, so I'm fairly sure it's not my config.

I've checked the logs that I know about and there is nothing other than "No output!" Has anyone else had a similar experience? I'm not a Perl programmer so perhaps this script is messed up, but I figured if that were the case though, it wouldn't function from the command line either.

About as far as I've gone with changing the script was to make sure that it was actually returning the exit status's that Nagios uses to determine if something is Ok, Warning, or Critical. It seems to be returning those values correctly. Any suggestions? Thanks!

Max
