-----------------------------------
Summary: Include offset information to spout metrics and remove
storm-kafka-monitor
Key: STORM-3202
URL: https://issues.apache.org/jira/browse/STORM-3202
Project: Apache Storm
Issue Type: Improvement
Affects Versions: 2.0.0
Reporter: Jungtaek Lim
Assignee: Jungtaek Lim
To provide offset information on Kafka spout (old and new), we have
storm-kafka-monitor module which is being run by UI (shell). This approach
requires UI doing too many things - basically UI process does most of things
via interacting with Nimbus - and also running external shell process in UI
process per opening topology page doesn't look right.
We could just let Spout include offset information into spout metric, and let
UI leverage the information. I have been thinking about this approach but
forgot about addressing it while thinking about generalizing the format. Now I
think we don't have to put too much effort to generalize format, because Kafka
spout is used mainly.
