Monitor gearmand

[spellen]

Anybodyn know howto monitor count jobs? And state of gearmand.
It`s need for cacti graph.

You can telnet to a gearmand server and use the output of the "status"
command. More details can be found here http://gearman.org/?id=protocol
in the section titled "Administrative Protocol". I've created a
Nagios plugin that we use to monitor the status of our workers. The
code is below for your reference.

#!/usr/bin/perl -w
use strict;
use Getopt::Long;
use Net::Telnet;

my $options = { 'k' => '', 'H' => 'localhost', 'r' => 4730, 'w' => 25,
'c' => 50 };

GetOptions($options, "k=s", "H=s", "r=i", "w=i", "c=i");

if (defined $options->{'help'}) {
print <<INFO;
$0: Check the status of gearmand job queues. {
}.

check_gearmand.pl -k workername [ -H <hostname> ] [ -r <port> ] [ -w
<warning> ] [ -c <critical> ]

-k <workername> - Name of the worker to check
-H <hostname> - Host where gearmand is running (default:
localhost)
-r <port> - Port number gearmand is listening on (default: 4730)
-w <position> - Number of jobs in queue for warning state
(default: 25)
-c <position> - Number of jobs in queue for critical state
(default: 50)
--help - This help page

INFO
exit;
}

if ( !defined $options->{'k'} || !defined $options->{'H'} || !defined
$options->{'r'} || !defined $options->{'w'} || !defined $options->
{'c'} )
{
print "ERROR: invalid input";
exit 3;
}

my $worker = $options->{'k'};
my $host = $options->{'H'};
my $port = $options->{'r'};
my $warn_threshold = $options->{'w'};
my $critical_threshold = $options->{'c'};
my $return_status = 2;
my $return_string = "GEARMAND CRITICAL: Worker not registered with
server\n";

# Connect to the gearmand server
my $telnet = new Net::Telnet( Host => $host, Port => $port , Timeout
=> 10, Errmode => sub{&telnet_error} );
$telnet->print( "status" );
my ($status) = $telnet->waitfor('/\./');
$telnet->close;

# Process the output from telnet
my @rows = split(/\n/, $status);
foreach ( @rows )
{
my @line = split(/\t/);
my $line_worker = $line[0];

if ( $line_worker eq $worker )
{
my $queued = $line[1];
my $running = $line[2];
my $available = $line[3];

if ( $queued < $warn_threshold )
{
# set OK
$return_status = 0;
$return_string = "GEARMAND OK: $line_worker -> avail: $available,
run: $running, queue: $queued\n";
}
elsif ( $queued < $critical_threshold )
{
# set warning
$return_status = 1;
$return_string = "GEARMAND WARN: $line_worker -> avail: $available,
run: $running, queue: $queued\n";
}
else
{
# set critical
$return_status = 2;
$return_string = "GEARMAND CRITICAL: $line_worker -> avail:
$available, run: $running, queue: $queued\n";
}
last;
}
}

# Return our findings to nagios
print $return_string;
exit $return_status;

sub telnet_error
{
print "ERROR: Telnet Connection Failed!\n";
exit 3;
}

Thanks a lot %)))

You can't count jobs in cacti as there is no counter in the stats. This
is on the roadmap, but not there yet.
