Does your plugin output one and only one line of text?

Yes, do you not see the status being set properly? It's probably better
to import utils.pm and exit using the name just in case the exit codes
change in the future --

#! /usr/bin/perl -w

use strict;
use lib "/usr/local/nagios/libexec"  ;
use utils qw(%ERRORS &print_revision &support &usage);

then you can 

print "<your plugin output>";
exit $ERRORS{'OK'};
# or
exit $ERRORS{'WARNING'};
# or
exit $ERRORS{'CRITICAL'};
# or 
exit $ERRORS{'UNKNOWN'};
