> For debugging purpose it would be very useful to have a log4j metric reporter. If you
don't want to setup a metric backend you currently have to rely on JMX, which a) works a bit
differently than other reporters (for example it doesn't extend AbstractReporter) and b) makes
it a bit tricky to analyze results as metrics are cleaned up once a job finishes.
