Applying MDC to stacktraces
Hi folks,
I'm looking to migrate from log4j1 to 2 and i'm wondering if there's any
way of making MDC prefixes appear on all stack trace lines. In 1 I had to
override subAppend in RollingFileAppender and I'm hoping I don't need to go
through similar pain in 2.
Thanks
Paul

Did this happen, if so how do I drive it.
Just to clarify:
This is what I have
DEBUG|0222-164903753|main|foo.LogStuff|1fac9d11-484a-4fda-8bbf-fa1b9cb5d73c|bCodeGoesHere|cCodeGoesHere|||hello
world
ERROR|0222-164903753|main|foo.LogStuff|1fac9d11-484a-4fda-8bbf-fa1b9cb5d73c|bCodeGoesHere|cCodeGoesHere|||Something
bad happened
java.lang.Exception: hahahahaha
at com.foo.LogStuff.logStuff(LogStuff.java:32)

This is what I want

Haven’t even thought about it yet. Probably a couple of weeks. I’d like to actually see if I can’t work on a couple of Jira issues this weekend.

Curious: When are we thinking WRT 2.5?

A couple of new features have been added that should help you:
1. Log4j now supports a PatternSelector so you can have multiple patterns specified for an appender.
2. A new unreleased feature (it will be in 2.5) is the ability to using Scripting on the PatternSelector. With that you can write a script and if the LogEvent contains an exception then you would choose the Pattern that includes the MDC information.
