Konstantin Knauf updated FLINK-9652:
------------------------------------
Issue Type: Improvement (was: Task)
As part of https://issues.apache.org/jira/browse/FLINK-22029 the "Task" Issue
Type is removed. I move this ticket to "Improvement". If you think "New
Feature", "Technical Debt" or "Bug" is more appropriate, please change the
ticket accordingly.
> Metrics for upstream and downstream
> -----------------------------------
>
> Key: FLINK-9652
> URL: https://issues.apache.org/jira/browse/FLINK-9652
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Metrics
> Reporter: Godfrey He
> Priority: Major
> Labels: metrics, sink, source, stale-major
>
> Flink can get metrics from source to the next operators，but can not get the
> total input/output metrics from web UI, which is inconvenient for user to get
> the records status for job.
> # Upstream and downstream metrics is import for troubleshooting.
> # No source input metrics, making many users considered that no kafka input
> at all, and Flink or Flink program might have some error. The same problem
> for the sink output metrics.
> # For some one operator job(just source and sink in the same operator
> chain), user cannot see any stream metrics, unless adds an keyBy operation,
> which will print the source output metrics.
