title: Parse a log4j log file
body: <p>We have several applications that use log4j for logging. I need to get a log4j parser working so we can combine multiple log files and run automated analysis on them. I'm not looking to reinvent the wheel, so can someone point me to a decent pre-existing parser? I do have the log4j conversion pattern if that helps.</p>
  
  <p>If not, I'll have to roll our own. </p>
