Re: [DISCUSS] KIP-736: Report the true end to end fetch latency

[Kai Huang <ka...@gmail.com>]

Hi all,

I'd like to bump up this discussion thread on KIP-736. 

I think this would be a useful metric from a monitoring perspective especially when troubleshooting or diagnosing issues. I've tested the fetch latency metric in Twitter's production environment, and provided some examples to illustrate how this metric can be used:

Please give it a look and let me know what you think.
