Sadly there is no documentation for this plugin

#!/usr/bin/perl -w
#
# xmlrpc based munin plugin for monitoring rtorrent's peer count
# prerequisites:
#  - rtorrent 0.7.5 or newer compiled with --with-xmlrpc-c
# check http://libtorrent.rakshasa.no/wiki/RTorrentXMLRPCGuide for further information

#
# 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"
#  category      Change graph category
#
# Configuration example
#
#       [rtom_allsessions_*]
#       user username
