# check http://libtorrent.rakshasa.no/wiki/RTorrentXMLRPCGuide for further information
#
# written by Gabor Hudiczius

#
# 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
#
# Configuration example
#
#	[rtom_vol]
#	user username
#	env.src socket
#	env.socket /home/user/torrent/.socket/rpc.socket
