Plugin to monitor Wowza streaming servers.

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:
<default> 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
