# xmlrpc based munin plugin for monitoring rtorrent's memory usage
# prerequisites:
# - rtorrent 0.7.5 or newer compiled with --with-xmlrpc-c
# check http://libtorrent.rakshasa.no/wiki/RTorrentXMLRPCGuide for further information

#
# 0.2.0 - 080619
# support for scgi_port and scgi_local
# configurable via munin env variables
# initial release
#
#
# Parameters:
#
# config required
#
#
# Configurable variables
#
# src "socket" when using scgi_socket, or anything else when using scgi_port
# socket rTorrent's rpc socket (scgi_local) - using scgi_local - needed, when "src" is set to "socket"
# ip rTorrent's ip address - using scgi_port - needed, when "src" is NOT set to "socket"
# port rTorrent's scgi port (scgi_port) - using scgi_port - needed, when "src" is NOT set to "socket"
# category Change graph category
# api use 'legacy' (pre 0.9.0) or current (0.9.0+) API calls
#
# Configuration example
#
# [rtom_allsessions_*]
# user username
# env.src socket
# env.socket /home/user/torrent/.socket/rpc.socket,/home/user/torrent/.socket/rpc.socket
# env.category Category
# env.api current
#
# [rtom_allsessions_*]
# user username
# env.port 5000,5001,5002,5003
