+# 
+# Munin plugin for ejabberd.
+#
+# Written by Lasse Karstensen <lkarsten@hyse.org> 2007-05-27.
+# Based on ejabberd-plugin by Christian Dröge <Christian@draugr.de>
+#
+# 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       
+#
+# use ln -s ejabberd ejabberd_(connections|users|registrations) 
+# 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.)
