Dear Team,

As per the tutorial “[How to do adaptive bitrate streaming](https://www.wowza.com/docs/how-to-do-adaptive-bitrate-streaming)” i have configured the smil file with big buck bunny videos, and i can able to play the smil file. Here my doubt is among the 4 files (450,700,1100,1500 KBPS) which one is playing (i am playing on my desktop machine).

Hi,

The fastest way to check which video is being played back by your player would be to check Wowza logs. You should be able to see the VOD request coming in from the player.

Also, you can use JWPlayer as described in the How to use [LongTail JW Player with adaptive bitrate streaming from Wowza Media Server](https://www.wowza.com/docs/how-to-use-jw-player-with-adaptive-bitrate-streaming-from-wowza-streaming-engine) article, or Flowplayer using the [bandwidth check plugin](http://flash.flowplayer.org/plugins/streaming/httpstreaming.html).

Hi,

When you say that you can see which bitrates are being used, do you mean that you can see the file name (containing bitrate information) being played back, or you can see the actual bitrate of the stream that is being played back?

You may need to enable httpAdapterDebugLog in VHost.xml Properties so Wowza will log the switching.

Here is a guide that shows how to[enable httpAdapterDebugLog via Engine Manager](https://www.wowza.com/docs/how-to-do-mpeg-dash-streaming#debuglogging)
