---------------------------------------
[~becket_qin] Thanks for the attention! I've already drafted a
[patch|https://github.com/apache/flink/pull/23998] for review. Agree that we'll
need a FLIP, I'll draft one for discussion.
> Display source/sink numRecordsIn/Out & numBytesIn/Out on UI
> -----------------------------------------------------------
>
> Key: FLINK-33681
> URL: https://issues.apache.org/jira/browse/FLINK-33681
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Metrics
> Affects Versions: 1.18.0, 1.17.2
> Reporter: Zhanghao Chen
> Priority: Major
> Labels: pull-request-available
> Attachments: screenshot-20231224-195605-1.png,

>
> Currently, the numRecordsIn & numBytesIn metrics for sources and the
> numRecordsOut & numBytesOut metrics for sinks are always 0 on the Flink web
> dashboard.
> FLINK-11576 brings us these metrics on the opeartor level, but it does not
> integrate them on the task level. On the other hand, the summay metrics on
> the job overview page is based on the task level I/O metrics. As a result,
> even though new connectors supporting FLIP-33 metrics will report
> operator-level I/O metrics, we still cannot see the metrics on dashboard.
> This ticket serves as an umbrella issue to integrate standard source/sink I/O
> metrics with the corresponding task I/O metrics.
