# Munin plugin for ejabberd2.
|
|
#
|
|
# Written by Lasse Karstensen <lkarsten@hyse.org> 2007-05-27.
|
|
# Based on ejabberd-plugin by Christian Dröge <Christian@draugr.de>
|
|
#
|
|
# Status, memory, threads, uptime, usersindays, ejabberd2 and other code
|
|
# optimisation 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.
