# 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 information

#

# 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"

#	category        Change graph category

#	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

#	env.category Sometext

#

#	[rtom_spdd]

#	env.ip 127.0.0.1

#	env.port 5000
