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.
