Return code of 9 is out of bounds when plugin is runin nagios, but return code is 0 when run from shell

[Kimberly McKinnis]

I got something similar when my script didn't have permission to run as the nagios user. It looks like you've ruled that out by running it by hand as nagios.

Are you piping this through nrpe and calling it from the nagios server? Can you call nrpe to the client machine from the nagios server on the command line?  I.e. check_nrpe -H <client machine> -n -c /usr/lib/nagios/plugins/<script> -w <threshold> -c <threshold>

Hi

Does anyone know what’s causing this error? I am utterly stumped.

Hello

I am having an issue with a plugin I just wrote where the Nagios says the return code is 9. If I do the following:

lnm at PR-LNM-CR-NAG01:/usr/local/nagios/libexec$ sudo -u nagios ./check_snmp_mw_local_rx_power.pl --hostname 192.168.27.140 --rocommunity EMSOLUTIONS --snmp-version 1
CHECK_RX_POWER OK - Local RX Power OK (-47.5dBm), |'local_RX_Power'=-47.5;-67;-100;;
lnm at PR-LNM-CR-NAG01:/usr/local/nagios/libexec$ echo $?
0

It suggests the return code is 0.

I have disabled the embedded perl interpreter.

Can anyone tell what is going wrong?

Plugin source code below:

#!/usr/bin/perl

=pod

=head1 NAME

Name of plugin and a sentence explaining function

-head2 SYNOPSIS

Detailed explanation of what the check does, any caveats, etc.
