How do you generate log files using ActionScript 3?

Is there any way to log activity using AS3 by using a Red5 Media Server?

I cam across www.as3commons.org/as3-commons-logging but in this I have no clue how to access logfiles or where the logfiles are generated.

I was wondering if there's a way to generate and store log files on a media server. Say for example, I need to log when the user starts recording a video, when the connection to the media server is successful and so on.

Any help would be greatly appreciated. Thanks.
