Hi , Is there any possibility to monitor per stream Bandwidth utilization in Wowza using log file ?. I tried , but couldn’t identify which entry that need to used for monitor. As cs-bytes shows huge amount of value like 1GB for single test stream request.

Hi, You can see the log4j field definitions in the [user guide](https://www.wowza.com/resources/WowzaStreamingEngine_UsersGuide.pdf). cs-bytes is a cumulative total transferred from client to server. You may find cs-stream-bytes useful - it’s the cumulative total number of bytes transferred from client to server for the stream referenced at x-stream-id. Paul ---

I could see the value for cs-stream-bytes on stop action. From the log file, I split up the values to corresponding metric cs-bytes --\> 2014599101 sc-bytes --\> 3817 x-stream-id --\> 5306327 cs-stream-bytes --\> 422606 sc-stream-bytes --\> 0 x-sname --\> 5268043 x-sname-query --\> test Here what is use of x-sname ?. Is the x-stream-id unique ? . In what metric, this ID is generated ?. In what scenario, this value will help us . Also, Is there any option to monitor per stream BW utilization via API Url Method [like [http://10.11.12.122:8086/connectioncounts](http://10.11.12.122:8086/connectioncounts) ] ?. Thanks. ---

Hi kgmsan, I am not 100% sure I fully understand your request. Anyway, we have a tool that reports the bandwidth per stream (among other things). You can try our free eval at [https://www.streamanalyst.com/free-account/](https://www.streamanalyst.com/free-account/) . Jean-Luc
