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

#
# 0.0.0 - 071218
#  initial release
#
# 0.0.1 - 071220
#  minor textbugs fixed
#
# 0.1.0d - 080519
#  full rewrite in perl
#  support for scgi_port and scgi_local
#  configurable via munin env variables
#  different ul/dl scale can be set for asymmetric connections
#  using get_(up|down)_total, and derive
#
# 0.2.0 - 080619
#  upload and download limit displayed on the graph
#
#
# 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"
#
#	diff		"yes" for using bps for upload and Bps for download, or anything else for using Bps for both
#
#
# Configuration example
#
#	[rtom_spdd]
#	user username
#	env.src socket
#	env.socket /home/user/torrent/.socket/rpc.socket
#
#	[rtom_spdd]
#	env.ip 127.0.0.1
#	env.port 5000
