# Plugin to monitor the number of connections to RabbitMQ
#
# Usage: Link or copy into /etc/munin/node.d/
#
# Parameters
# env.conn_warn <warning connections>
# env.conn_crit <critical connections>
#
# 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 wether we
# should be run on this system or not. This is optinal, 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
HOME=/tmp/
# If run with the "config"-parameter, give out information on how the
# graphs should look.
if [ "$1" = "config" ]; then
CONN_WARN=${queue_warn:-500}
CONN_CRIT=${queue_crit:-1000}
# The host name this plugin is for. (Can be overridden to have
# one machine answer for several)
# The title of the graph
echo 'graph_title RabbitMQ connections'
# Arguments to "rrdtool graph". In this case, tell it that the
# lower limit of the graph is '0', and that 1k=1000 (not 1024)
echo 'graph_args --base 1000 -l 0'
# The Y-axis label
echo 'graph_vlabel connections'
# We want Cur/Min/Avg/Max unscaled (i.e. 0.42 load instead of
# 420 milliload)
#echo 'graph_scale no'
echo 'graph_category RabbitMQ'
echo "connections.label Connections"
echo "connections.warning $CONN_WARN"
echo "connections.critical $CONN_CRIT"
echo "connections.info Number of active connections"
echo 'graph_info Shows the number of connections to RabbitMQ'
# Last, if run with the "config"-parameter, quit here (don't
# display any data)
exit 0
fi
# If not run with any parameters at all (or only unknown ones), do the
# real work - i.e. display the data. Almost always this will be
# "value" subfield for every data field.
echo "connections.value $(HOME=$HOME rabbitmqctl list_connections | grep -v "^Listing" | grep -v "done.$" | wc -l)"
