I have tried two reporter types (Graphite, JMX) Graphite metrics.reporters: grph metrics.reporter.grph.class: org.apache.flink.metrics.graphite.GraphiteReporter metrics.reporter.grph.host: xxxxxxxxxxxxxxxx metrics.reporter.grph.port: 2003 metrics.reporter.grph.protocol: TCP
What I see on graphite are incomplete metrics. Some taskIdx (same process) will show different sets of metrics. For example, - Sink->test - 0: currentInputWatermark, numRecordsIn - 1: numRecordsOutPerSecond - 2: numRecordsIn, numRecordsOut - 4: currentInputWatermark I would expect seeing - Sink->test - 0: currentInputWatermark, numRecordsIn, numRecordsOut, numRecordsOutPerSecond, numRecordsInPerSecond... - 1: currentInputWatermark, numRecordsIn, numRecordsOut, numRecordsOutPerSecond, numRecordsInPerSecond... - 2: currentInputWatermark, numRecordsIn, numRecordsOut, numRecordsOutPerSecond, numRecordsInPerSecond... - 4: currentInputWatermark, numRecordsIn, numRecordsOut, numRecordsOutPerSecond, numRecordsInPerSecond... JMX metrics.reporters: jmx metrics.reporter.jmx.class: org.apache.flink.metrics.jmx.JMXReporter metrics.reporter.jmx.port: 8789 I used visualvm with mbean explorer to view the exposed mbeans. In this setup, I do see the expected metrics but the organization makes it difficult to find [cid:image002.png@01D432FF.AE632750] I also get the following WARNing 2018-08-09 18:36:55,943 WARN org.apache.flink.runtime.metrics.MetricRegistryImpl - Error while reporting metrics java.util.ConcurrentModificationException at java.util.LinkedHashMap$LinkedHashIterator.nextNode(LinkedHashMap.java:719) at java.util.LinkedHashMap$LinkedKeyIterator.next(LinkedHashMap.java:742) at java.util.AbstractCollection.addAll(AbstractCollection.java:343) at java.util.HashSet.<init>(HashSet.java:120) at org.apache.kafka.common.internals.PartitionStates.partitionSet(PartitionStates.java:65) at org.apache.kafka.clients.consumer.internals.SubscriptionState.assignedPartitions(SubscriptionState.java:298) at org.apache.kafka.clients.consumer.internals.ConsumerCoordinator$ConsumerCoordinatorMetrics$1.measure(ConsumerCoordinator.java:906) at org.apache.kafka.common.metrics.KafkaMetric.value(KafkaMetric.java:61) at org.apache.kafka.common.metrics.KafkaMetric.value(KafkaMetric.java:52) at org.apache.flink.streaming.connectors.kafka.internals.metrics.KafkaMetricWrapper.getValue(KafkaMetricWrapper.java:37) at org.apache.flink.streaming.connectors.kafka.internals.metrics.KafkaMetricWrapper.getValue(KafkaMetricWrapper.java:27) at org.apache.flink.dropwizard.metrics.FlinkGaugeWrapper.getValue(FlinkGaugeWrapper.java:36) at com.codahale.metrics.graphite.GraphiteReporter.reportGauge(GraphiteReporter.java:279) at com.codahale.metrics.graphite.GraphiteReporter.report(GraphiteReporter.java:169) at org.apache.flink.dropwizard.ScheduledDropwizardReporter.report(ScheduledDropwizardReporter.java:231) at org.apache.flink.runtime.metrics.MetricRegistryImpl$ReporterTask.run(MetricRegistryImpl.java:427) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:308) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$301(ScheduledThreadPoolExecutor.java:180) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:294) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) I am using flink 1.5.1 J.

Can you provide us with the metrics section of your flink-conf.yaml? Are there any metric-related warnings in the TaskManager logs?

I have followed instructions in https://ci.apache.org/projects/flink/flink-docs-release-1.5/monitoring/metrics.html - Added the flink graphite jar to taskmanager/jobmanager lib folder - confligured flink-conf.yaml to enable graphite reporter - Added a simple counter in my flink code When I submit the job, I can see my counter show up in the flink web ui's Task Metrics section. But the counter does not show up in Graphite. Also, the metrics that actually make it to Graphite doesn't seems like it's published properly. Is anyone actually using Graphite Reporter? What is your experience? What am I missing?
