Minecraft server logging configuration file for Minecraft 1.7.2+

log4j2.xml

Place the file to the same directory as your minecraft_server.jar, and add -Dlog4j.configurationFile=log4j2.xml to your server startup arguments.

The given configuration mimics the old logging behaviour.

If you want daily rolled logs, uncomment the <AppenderRef ref="rolling_server_log" /> line (and probably comment out the the legacy_server_log since you don't then want that?). For compressed rolled logs, add .gz to the end of the filePattern's filename pattern (logs/server_%d{yyyy-MM-dd}.log.gz).

Thanks! Saved me the time and hassle of doing this myself.

This is great, but it breaks the console output. I'm trying to figure out a solution.

How does it break it? It was supposed to work/output exactly the way it worked before 1.7, and afaik it does that on all of my servers.

I love my logs to be at one place, but it turns out, adding that option "-Dlog4j.configurationFile=log4j2.xml" makes my server eat 100%+ CPU time on empty and idle server. Do you have any idea why?
Its on Linux laptop 3.12.2-1-ARCH x86_64 GNU/Linux
and also on
Linux Ubuntu 2.6.35-22-server x86_64 x86_64 x86_64 GNU/Linux

Best regards

EDIT:
Well, https://gist.github.com/EvilSeph/7909975 works fine for me. Maybe I edited badly your xml, maybe not.

Thank you for this! I've been looking for a way to control Forge logging for some time.

sooo confused xD
