Joel Koshy updated KAFKA-921:
-----------------------------
Attachment: KAFKA-921-v1.patch
This provides a max lag mbean for both consumer fetcher manager and replica
fetcher manager; although I think it is more useful for monitoring consumers.
For replica fetchers we need to closely monitor all replica fetchers anyway.
i.e., the set of mbeans is static. I can reduce the scope to just consumers if
others agree.
> Expose max lag mbean for consumers and replica fetchers

> We have a ton of consumer mbeans with names that are derived from the
> consumer id, broker being fetched from, fetcher id, etc. This makes it
> difficult to do basic monitoring of consumer/replica fetcher lag - since the
> mbean to monitor can change. A more useful metric for monitoring purposes is
> the maximum lag across all fetchers.
