Munin contributed plugins

#!/bin/sh

#

# Plugin to monitor the queues of a virtual_host in RabbitMQ

#

# Usage: Link or copy into /etc/munin/node.d/

#

# Parameters

#     env.vhost <AMQ virtual host>

#     env.queue_warn <warning queuesize>

#     env.queue_crit <critical queuesize>

#

# Magic markers (optional - only used by munin-config and some

# installation scripts):

#

#%# family=auto

#%# capabilities=autoconf

# If run with the "autoconf"-parameter, give our opinion on whether we

# should be run on this system or not. This is optional, and only used by

# munin-config. In the case of this plugin, we should most probably

# always be included.

if [ "$1" = "autoconf" ]; then

	echo yes

	exit 0

fi

# If run with the "config"-parameter, give out information on how the

# graphs should look.
