icecast2_

Sadly there is no documentation for this plugin

#! /usr/bin/python
# -*- coding: iso-8859-1 -*-

import os
import sys
import urllib2
from xml.dom import minidom


# Hostname of Icecast server
# Just canonical name, no http:// nor ending /
host = "foo.bar.com"
username = "admin"
# Password for admin access to Icecast2 server to fetch statistics
password = ""
realm = "Icecast2 Server"

# Bitrates the MP3 stream is served with
mp3bitrates = [56, 128]
# Bitrates the Ogg Stream is served with
oggbitrates = [56, 128, 172]

# 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
