I was searching for a Nagios plugin to monitor RabbitMQ, and only found an unanswered question to this mailing list of how it could be done.

I wanted to share the Ruby code I wrote for monitoring queue size. A next step for monitoring is to connect directly to the queue with the Bunny gem and make sure it is accepting connections.

#########

#!/usr/bin/ruby

VERSION_STRING = "Cloudspace RabbitMQ queue size checker v1.0 2009-10-20"


require 'optparse'

options = { :warning => 0, :critical => 0 }

OptionParser.new do |opts|

Tim,

You may want to supply the '-q' option to rabbitmqctl in order to
suppress the output of information messages ("Listing queues ..." ,
"...done", etc).


Regards,

Matthias.

Yep! Good addition.

Also to note: you will probably have to configure sudoers to allow nagios to run rabbitmqctl without prompting for a password. Use the following line

nagios

Cool, I didn't know about -q.

You can even restrict it to specific rabbitmqctl subcommands, for my
munin plugins[1] I use:

munin ALL= NOPASSWD: /usr/sbin/rabbitmqctl list_queues *
munin ALL= NOPASSWD: /usr/sbin/rabbitmqctl list_connections

This way you don't give it access to stop, reset etc.
