# Munin plugin for ejabberd2.
#
# Written by Lasse Karstensen <[email protected] > 2007-05-27.
# Based on ejabberd-plugin by Christian Dröge <[email protected] >
#
# Memory, threads, ejabberd2 and other code
# optimisation by Peter Viskup <[email protected] >
#
# 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_memory
# ejabberd_threads
# ejabberd_mnesia_records
# ejabberd_mnesia_memory
#
# use command
# ln -s ejabberd_ ejabberd_(connections|memory|registrations|threads|users|ejabberd_mnesia_memory|ejabberd_mnesia_records)
# to activate.
#
# If the autodetect-feature for vhosts breaks, you can set
# """
# [ejabberd_*]
# env.vhosts foo.com bar.com
# """
# in plugin-conf.d/munin-node to override it.
# (user root may also be smart/not so smart depending on your setup.)
# Be aware that datasource name of rrdtool is restricted to 19 characters maximum. It could lead to not working plugin if vhost string is too long.
