Summary: UI Visualizations
Key: STORM-69
URL: https://issues.apache.org/jira/browse/STORM-69
Project: Apache Storm (Incubating)
Issue Type: New Feature
Reporter: James Xu
https://github.com/nathanmarz/storm/issues/368
I've worked with Storm for a while now, and I can say that having a quick
visual on the makeup of your topologies is worth a lot. It's far easier to
simply look at a graph, and see the connections between named nodes, than to
browse through code. Invaluable when you're debugging a problem in production.
Along these lines, I think it would be a real asset to have a handful of useful
visualizations in the UI.
One example would be circle packing, where the containing circles are
topologies, and the inner circles are topology components. See
http://mbostock.github.com/d3/talk/20111116/pack-hierarchy.html. The idea would
be to write it flexibly, so that the size of each circle is given by a function
over the topology and/or node. You could imagine representing such things as
throughput, latency, (received - acked), (# of executors occupied), etc in this
way. It would be a quick visual indicator of how your topologies are behaving.
Another example would be if you wanted a quick visual depiction of a topology
-- you might use a graph, or a force-directed graph:

Many more ideas here: https://github.com/mbostock/d3/wiki/Gallery
If you guys think any of these would be a valuable addition, I'd love to take a
crack at it.
----------
nathanmarz: I would like to see a force-directed graph of each topology, with
the size of the edges between nodes indicating the amount of throughput passing
between them. Once we improve the metrics (notably issues #362 and #363) we can
use color to indicate which components are likely bottlenecks in the topology.
It would be really cool if clicking on a node shows more detailed information
(like a visualization of the incoming and outgoing throughput to each
individual task in that component).

gsilk: I'm on it.

chenxiaozhao: i can‘t wait to see the force-directed graph ,which can show the
incoming and outgoing throughput to each individual task in that component
