Ewen Cheslack-Postava commented on KAFKA-2376:
----------------------------------------------
Not quite a direct comparison, but some helpful ideas about framework-level
metrics we could add:

One thing we found super helpful in samza was giving a metric that rolls up the
percent of time getting records, time processing records, and time sending
records to be able to debug these bottleneck issues. Technically you can kind
of get this from the clients, but might be nice to roll that up to make it easy.

We still will need to expose connector-specific metrics, but these are generic
ones that can add a lot of value.
