Usage: - Link or copy to /etc/munin/plugins - To enable extra graphs, also link to one or more of the possible links (given below) - Then restart munin-node Links possible: total number of listeners in wowza wowza_duration duration of listeners (avg and mdn) wowza_vhost_listeners number of listeners per vhost wowza_vhost_duration duration of listeners per vhost wowza_vhost_uptime uptime of vhosts wowza_app_listeners number of listeners per application wowza_app_duration duration of listeners per application wowza_app_uptime uptime of applications Configuration: - Enter your server, username, and password below (The plugin does not need to run on the same host as the Wowza media server) - Optionally provide clients to exclude - Optionally provide apps to exclude - Optionally provide vhosts to exclude Possible TODOs: - use autoconf - use munin's configuration system """ from __future__ import print_function from sys import argv, exit, stderr import urllib2 from xml.etree.ElementTree
