[Nagiosplug-devel] Custom Plugin issue

[Frank Reta]

Hello:

            Not sure if these are the correct forums through which to
ask questions, but I couldn't find where else to post to.

 

Nagios 1.2 on Fedora 3

 

I'm in the throes of trying to create an in-house script that parses a
file for a given number.  It then uses this number to determine if the
return should be OK, WARNING or CRITICAL.  When command line run, the
issued PRINT line displays the correct result given the parameters
given.  When brought into Nagios, the "Status Information" portion of
the service item is correct, but the actual "Status" entry never changes
from OK, despite the plugin reporting "Critical".

 

The perl script is:

 

#!/usr/bin/perl -w

 

use strict;

use warnings;

use Getopt::Long;

 

use constant STATS_FILE_PATH =>
'/home/kapow/crawler/etc/crawl-server.stat';

 

my @return_codes = qw( OK WARNING CRITICAL UNKNOWN );

 

 

my ($warning, $critical) = get_cmd_params();

my $threads = 0;

my $status = 0;

my $msg = '';

 

if( open( STAT, STATS_FILE_PATH ) ) {

 

    foreach ( <STAT> ) {

        next unless /^threads=(\d+)/;

        $threads = $1;

    }

    close( STAT );

    $status = ( $threads > $warning ) ? 0 :

        ( $threads > $critical ) ? 1 : 2;

    $msg = "crawl-server currently has $threads threads";

} else {

    $status = 3;

    $msg = 'unable to open crawl-server stats file';

}

 

 

print( "threads $return_codes[$status] - $msg ",

       "|threads=$threads;$warning;$critical;$status\n" );

 

 

 

######################################################################

sub get_cmd_params {

 

    my ($warning, $critical) = (0,0);

 

    my $result = GetOptions( 'w=i' => \$warning,

                             'c=i' => \$critical );

 

    die "Usage: get_crawler_stats -w <threads> -c <threads>\n"

        if($warning <= 0 || $critical <= 0);

 

    return ($warning, $critical);

}

 

 

 

When run on command line, the result is:

[root at warlords etc]# /usr/local/nagios/libexec/check_nrpe -H crawl1 -c
check_threads -a 70 60

threads WARNING - crawl-server currently has 64 threads
|threads=64;70;60;0

 

(to compare, the check_users, which does work correctly all the way
through is:) 

[root at warlords libexec]# ./check_users -w 1 -c 6

USERS WARNING - 5 users currently logged in |users=5;1;6;0

 

 

Any help on this would be immensely appreciated.  If this is not the
correct forum to direct my questions to, could you please point me in
the right direction?

 

Thanks much!
