Hi,
Thanks for your answer.
But now we get NaN in the 'Task Metrics' in the Web UI.
And there's no metric for latency when we attempted to export the metrics
through Prometheus either.
Then, we attempted to export the metrics through slf4j, I found that it
works. One of the logs is as follows:
"10.203.87.73.taskmanager.e65b594c3a725912566dd631b005c1cc.Flink Streaming
RWKafka.Flat Map.0.latency: {LatencySourceDescriptor{vertexID=1,
subtaskIndex=-1}={p95=2260.1, min=2.0, mean=247.4375, max=3336.0,
p99=3041.069999999994, p50=61.5}}"
What do you think about Flink-7608
<https://issues.apache.org/jira/browse/FLINK-7608> and Flink-6053
<https://issues.apache.org/jira/browse/FLINK-6053>. It is advisable to do
so.
Thank you very much.
