-------------------------------------
Assignee: (was: Robert Metzger)
> Show latency statistics in web interface
> ----------------------------------------
>
> Key: FLINK-4830
> URL: https://issues.apache.org/jira/browse/FLINK-4830
> Project: Flink
> Issue Type: Sub-task
> Components: Metrics, Webfrontend
> Reporter: Robert Metzger
> Fix For: pre-apache
>
>
> With FLINK-3660, we added a metric that measures the latency of records
> flowing through the system.
> With this JIRA, I would like to expose the latency also in the web frontend.
> Therefore, we'll probably need to change the format the latency is reported
> in the metric.
> I think we should show the latencies in two different views in the interface:
> - A global end-to-end latency in the overview of running jobs. This number is
> probably pretty inaccurate, but should give users a first impression of the
> latency characteristics currently present in the job
> - A detailed latency drill-down view, that allows to see how much latency is
> added on average at each operator, for the sources.
