---------------------------------------
was (Author: zhanghao chen):
After further investigation, it turned out to be a bug introduced by
FLINK-30536, which changed the way to count task-level I/O metrics and
accidentally stopped reusing source/sink-writer operator I/O metrics for task
I/O metrics. Converting the issue to a bug.

> 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

> Currently, the numRecordsIn & numBytesIn metrics for sources and the
> numRecordsOut & numBytesOut metrics for sinks are always 0 on the Flink web
> dashboard.
> [FLINK-11576|https://issues.apache.org/jira/browse/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.
