Logging. An old friend. So critical for a production deployment and so hidden away. Much has been said and done in this area, and we’ve seen both success and total domination by log4j, as well as an abysmal failure of java.util.logging (still hearing the chorus of WTFs and raised eye brows).
With the introduction of Mule 3 the playing field has changed dramatically, but something was still missing. Multiple applications in runtime were still writing to the same single log file.
