Understand Selinum Java logs (and disabling it)

[Paulo Eduardo Neves]

When I run my Java/JUnit Selenium webdriver tests, I'm overwhelmed with log messages. Here are some examples:

1484238833185    addons.xpi    DEBUG    Calling bootstrap method startup on fir...@getpocket.com version 1.0.5
1484238833202    addons.manager    DEBUG    Completed startup sequence

How do I configure these logs. The docs just report 6 types of log:

        loggingPrefs.enable(LogType.BROWSER, Level.WARNING);
        loggingPrefs.enable(LogType.CLIENT, Level.WARNING);
        loggingPrefs.enable(LogType.DRIVER, Level.SEVERE);
        loggingPrefs.enable(LogType.PERFORMANCE, Level.WARNING);
        loggingPrefs.enable(LogType.PROFILER, Level.WARNING);
        loggingPrefs.enable(LogType.SERVER, Level.WARNING);

How do I know from which one each message belongs?

How do I disable the INFO/DEBUG messages?

I've tried a lot of this, but I think I don't really understand the log handling in Selenium.
