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.
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="mdcKeysToUse" 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
