If you use the ?flat query parameter when accessing this HTTP Provider, it produces a simplified list of streams and counts.

This provider is built into Wowza media server software at com.wowza.wms.http.HTTPConnectionCountsXML and can be accessed at:

http://[wowza-ip-address]:8086/connectioncounts
http://[wowza-ip-address]:8086/connectioncounts?flat

Be sure to add an admin user name and password to the [install-dir]/conf/admin.password file in order to access.
