             Summary: IMplement a log4j metric reporter
                 Key: FLINK-4831
                 URL: https://issues.apache.org/jira/browse/FLINK-4831
             Project: Flink
          Issue Type: Improvement
          Components: Metrics
    Affects Versions: 1.1.2
            Reporter: Chesnay Schepler
             Fix For: 1.2.0


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.
