# This plugin shows the statistics of a specific subset of sources connected to an Icecast2 server.
# Place the file in /usr/share/munin/plugins and then symlink to it from
# /etc/munin/plugins
# The name icecast2_total will show total number of listeners on server, as
# well the total number of listeners for any configured stream.
# For each stream with multiple bitrates, create one
# icecast2_streamname
# If the name contains a "-" exchange it with a "_", and the script will change it back for you. This is to satisfy internal requirements of Munin.
# For each streamname, the plugin will check for the configured bitrates
# Expecting the mountpoints to be on the form of
# /streamname_<bitrate> for mp3
# /streamname_<bitrate>.ogg for Ogg/Vorbis
