check_snmp problem - no output help

[Starr, Neal (CCI-Wichita)]

I'm currently running into a problem with the check_snmp plugin for Nagios.  I'm attempting to walk a couple of specific OIDs on several hosts in my network.  When I use the following from the shell on my Solaris 9 box, everything works Ok:

$ ./check_snmp -H 172.26.49.9 -P 1 -o .1.3.6.1.2.1.10.127.1.1.4.1.5.8781827 -w 20:40 -c 15:40 -C xxxxxxxxxxxxxxx
SNMP OK - 24 


Verbose mode shows pretty much the same:

$ ./check_snmp -H 172.26.49.9 -C xxxxxxxxxxxxxxxx -P 1 -o .1.3.6.1.2.1.10.127.1.1.4.1.5.8781827 -w 20:40 -c 15:40 -v
/usr/local/bin/snmpget -t 1 -r 9 -m ALL -v 1 -c xxxxxxxxxxxxxxxx 172.26.49.9:161  .1.3.6.1.2.1.10.127.1.1.4.1.5.8781827
.1.3.6.1.2.1.10.127.1.1.4.1.5.8781827 = INTEGER: 23.4 dB

SNMP OK - 23


However when I then create a check command to do the same thing and a corresponding service to go with it, every host I point the service at just returns a current state of "warning" and the state information says "(No output!)"  Here is command definition:

# check CMTS1 US1 SNR
define command{
        command_name    check_blade1_us1_snr
        command_line    $USER$/check_snmp -H $HOSTADDRESS$ -C xxxxxxxxxxxxxxxx -P 1 -o .1.3.6.1.2.1.10.127.1.1.4.1.5.8781827 -w 20:40 -c 15:40
}    


>From a problem I had with a different plugin, I tried moving the location of the -C community string option around in the command line, but this has no effect.  I also tried removing the -c critical range option to see if maybe something was getting confused between the -C and -c options, but to no avail either.


Looking in nagios.log wasn't much help either as it stated basically the same thing:

[1068241877] SERVICE ALERT: hutccmta01;Check Blade 1 US1 SNR;WARNING;SOFT;2;(No output!)


Just hoping maybe someone knows what is wrong in here.  Many thanks.
