Yes, you can customize the logs extensively by editing [wowza-install-dir]/conf/log4j.properties file. This file has a number of Appenders, some are commented out, and all can be changed in various ways, including re-arranging log fields, or adding (there is a superset of all available fields shown in the file) and including categories and excluding events. The file itself has many comments that you can study, and there is a logging chapter in the user guide with more info.

Here is a some articles related to logging:

Yes, you will see examples of Appenders that use CategoryInclude, which excludes categories not listed, something like this:

```auto
log4j.appender.serverStats.layout.CategoryInclude=session

```

</div>

nevermind my previous question 🙂 ,

I saw this on user guide:

**x-category - Log event category (server, vhost, application, session, stream)**

my question now is, is it possible to log only the “Session” x-category? 🙂

THANKS,
