Description

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.
