Greg Hogan commented on FLINK-3160:
-----------------------------------
This commit I just pushed does use two tabs called "Tasks" (formerly
"Overview") and "TaskManagers". It is nice that the UI maintains the open task
when switching between tabs. Also, nesting multiple levels of expanding tables
does not work with the way the UI currently captures clicks such that clicking
anywhere on an expanded task closes that table.

> Key: FLINK-3160
> URL: https://issues.apache.org/jira/browse/FLINK-3160
> Project: Flink
> Issue Type: Improvement
> Components: Webfrontend
> Affects Versions: 1.0.0
> Reporter: Greg Hogan
> Assignee: Greg Hogan
>
> The web client job info page presents a table of the following per task
> statistics: start time, end time, duration, bytes received, records received,
> bytes sent, records sent, attempt, host, status.
> Flink supports clusters with thousands of slots and a job setting a high
> parallelism renders this job info page unwieldy and difficult to analyze in
> real-time.
> It would be helpful to optionally or automatically aggregate statistics by
> TaskManager. These rows could then be expanded to reveal the current per task
> statistics.
> Start time, end time, duration, and attempt are not applicable to a
> TaskManager since new tasks for repeated attempts may be started. Bytes
> received, records received, bytes sent, and records sent are summed. Any
> throughput metrics can be averaged over the total task time or time window.
> Status could reference the number of running tasks on the TaskManager or an
> idle state.
