Of course, in bash the local $MUNIN_DEBUG is the same as the

# Munin plugin for ejabberd2.
# This script supports versions 2.0 and 2.1 of ejabberd.
#
# Written by Lasse Karstensen <lkarsten@hyse.org> 2007-05-27.
# Based on ejabberd-plugin by Christian Dröge <Christian@draugr.de>
#
# Status, memory, threads, ejabberd2 and other code optimalisation
# by Peter Viskup <skupko.sk@gmail.com>
#
# As connected users, registered users and server-connections have somewhat
# different scales, this plugin uses munins suggest feature to create three
# different graphs.
#
# ejabberd_connections
# ejabberd_users
# ejabberd_registrations
# ejabberd_statuses
# ejabberd_memory
# ejabberd_threads
# ejabberd_usersindays
# ejabberd_uptime
#
# use ln -s ejabberd ejabberd_(connections|users|registrations|statuses|memory|threads|usersindays|uptime)
# to activate.
#
# If the autodetect-feature for vhosts breaks, you can set
