[jira] [Commented] (FLINK-4831) Implement a log4j metric reporter

    [ https://issues.apache.org/jira/browse/FLINK-4831?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15594771#comment-15594771 ] 

Robert Metzger commented on FLINK-4831:
---------------------------------------

So the Log4j metric reporter would periodically log the current values of all metrics?

> 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.
