-# Munin Wildcard Plugin for Deluge torrent client
-#
-# This plugin has 3 modes :
-# - connections : monitors the number of connections
-# - bandwidth : monitors the bandwidth (up, up overhead, down, down overhead)
-# - states : monitors the torrents' states
-#
-# To use one of these modes, link the this plugin with a name like 'deluge_<mode>'
-# For example :
-# ln -s /path/to/deluge_ /etc/munin/plugins/deluge_connections
-#
-# Use your "/etc/munin/plugin-conf.d/munin-node" to configure this plugin.
-# You must at least add :
-#   [deluge_*]
-#   user <user_with_access_to_deluge>
-#   env.HOME <path_to_deluge_user_home>
-#
-# By default, this plugin will try to access the deluge daemon with the following configuration :
-#   host 127.0.0.1
-#   port 58846
-#   no username
-#   no password
-#
-# You can change these settings in "plugin-conf.d/munin-node" :
-#   [deluge_*]
-#   user <user_with_access_to_deluge>
-#   env.HOME <path_to_deluge_user_home>
-#   env.host 127.0.0.1
-#   env.port 58846
-#   env.username user
-#   env.password pass
-#
-# By default, deluge configuration files will be searched under $XDG_CONFIG_HOME, which is by default set to $HOME/.config
-# Setting env.HOME allows this default to work. However, you can also explicitly set the env.XDG_CONFIG_HOME if needed.
