# 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"

#  category      Change graph category

#  api           use "pre09" (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
