This is a minimal template to get info about your wowza rest url in your Zabbix Platform.
Two items, by now:
Global connections in the Wowza
Global Live streams number
The template uses Zabbix macros to define the user/pass Wowza server url. It permits a fast configuration because of you can apply the same template to all your wowza hosts and to change the user/pass usermacros per host only.
