Hi,

I just want to use Logback as logger in my application, but wowza seems to use log4j as a default.(because it first finds a conf/log4j.properties?)

Thing is…

Could you tell me how I can configure the wowza log handling function? Thanks.

I suspect the problem you’ll find is that to implement this library would require a huge amount of effort in converting Wowza code and adding modules etc. It doesn’t appear to me to be a transparent replacement for log4j.properties.

Kind regards,

Paul

As an addendum to my last post, you could look at extending this by creating your own module using the iLogNotify API. This won’t be a simple drop in replacement, but could get you what you want if you’re comfortable with module development. See example from Charlie in this thread, [extending logging API in Wowza](https://www.wowza.com/forums/showthread.php?687-Accessing-cs-bytes-from-custom-app&p=3142#post3142).

Understood. Thank you, Paul.
