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 Streaming Engine™ 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. For more information, see Manage users with the Wowza Streaming Engine CLI password tool.
