-----------------------------------
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.
