json-log4j-layout

I started this project because I needed a fast way to export Log4j events into JSON
as part of my elasticflume project (https://github.com/tallpsmith/elasticflume).

I was a bit surprised to not easily Google an existing one, so if you do know of one
that’s awesome, by all means let me know..

I needed this one to be fast, and I believe Jackson is a very fast JSON renderer.

HowToBuild

This project uses mvn, just type:

   mvn package

and inside the “target” directory will be the JAR.

Configure this Layout as you would normally in log4j with the classname org.elasticflume.log4j.JSONLayout
If you use Log4j’s MDC (and really you should!) then add a parameter block to configure
the set of MDC keys you wish to export in this layout (CSV format for the keys)

 <param name="MdcsToUse" value="UserId,ProjectId,RequestId" />

TODO
====

Currently does NOT export locationInformation
I have not yet exported this Maven project to the OSS Sonatype Release repository for easy dependency Management for people
