[jira] [Created] (FLINK-10962) Allow correlations between subtask metrics and checkpoint metrics

             Summary: Allow correlations between subtask metrics and checkpoint metrics
                 Key: FLINK-10962
                 URL: https://issues.apache.org/jira/browse/FLINK-10962
             Project: Flink
          Issue Type: Improvement
          Components: Webfrontend
    Affects Versions: 1.7.0
            Reporter: Nico Kruber


Currently, if you click into a running job and look into the "Subtasks" tab, it will show all subtasks' metrics like received/send bytes/records, host name, status. If you browse into some checkpoint (in the "Checkpoints" tab), it will show the checkpoint statistics (size, buffer alignment, subtask ID). You cannot easily correlate the two, e.g. if you want to see whether a subtask with high input load also has large state.

I'd suggest to either add the subtask ID to the "Subtasks" view, or the hostname to the checkpoint details (or both). Even better would be a direct link to switch from one view to the other and preselecting a specific subtask.
