Hi Padarn If you want to verify why no metrics sending out, how about using the built-in Slf4j reporter [1] which would record metrics in logs. If you could view the metrics after enabled slf4j-reporter, you could then compare the configurations.

I was using the DataDogHttpReporter, but have also tried the StatsDReporter, but with both was seeing no metrics being collected. To debug this I implemented my own reporter (based on StatsDReporter) and logged the name of the metric being sent: private void send(final String name, final String value) { log.info("STATSD SENDING: ", name, value); try { String formatted = String.format("%s:%s|g", name, value); byte[] data = formatted.getBytes(StandardCharsets.UTF_8); socket.send(new DatagramPacket(data, data.length, this.address)); } catch (IOException e) { LOG.error("unable to send packet to statsd at '{}:{}'", address.getHostName(), address.getPort()); } } This code is certainly reached, because in my log I see a lot of this: 2019-05-30 10:18:40,351 INFO com.grab.statsd.StatsDReporter - STATSD SENDING: 2019-05-30 10:18:40,351 INFO com.grab.statsd.StatsDReporter - STATSD SENDING: 2019-05-30 10:18:40,351 INFO com.grab.statsd.StatsDReporter - STATSD SENDING: 2019-05-30 10:18:40,351 INFO com.grab.statsd.StatsDReporter - STATSD SENDING: 2019-05-30 10:18:40,351 INFO com.grab.statsd.StatsDReporter - STATSD SENDING: 2019-05-30 10:18:40,351 INFO com.grab.statsd.StatsDReporter - STATSD SENDING: 2019-05-30 10:18:40,352 INFO com.grab.statsd.StatsDReporter - STATSD SENDING: As you can see, the name and value for the metric being reported is empty. And the logs show everything initialized fine with no error: 2019-05-30 10:18:30,342 INFO org.apache.flink.runtime.metrics.MetricRegistryImpl - Configuring stsd with {port=8125, host=127.0.0.1, class=com.grab.statsd.StatsDReporter}. 2019-05-30 10:18:30,344 INFO com.grab.statsd.StatsDReporter - Configured StatsDReporter with {host:127.0.0.1, port:8125} 2019-05-30 10:18:30,344 INFO org.apache.flink.runtime.metrics.MetricRegistryImpl - Periodically reporting metrics in intervals of 10 SECONDS for reporter stsd of type com.grab.statsd.StatsDReporter. Has anyone else tried to work with Flink and metrics on EMR 1.7.1 (latest version on EMR). If so, any pointers as to what could be set up incorrectly? Grab is hiring.
