This is much needed monitoring and really great!
What are the current options for showing the detailed metrics? I see a
"show 3 TMs" and "show all TMs" button in the screenshot? Can you select which
three to show?
How about showing small indicators (load, % non-Flink-managed heap, GC
interval) with a simple color coding (red for hot, blue for cool). This would
help to find TMs which are more loaded than others. The detailed view could be
opened by clicking on the TMs.
But we do not need to get the perfect solution at once.
How about we open a document and sketch the design of the monitoring and
create smaller PRs to get there step-by-step.
This PR is definitely a huge step in the right direction!
