Subject Re: [DISCUSS]KIP-223 - Add per-topic min lead and per-partition lead metrics to KafkaConsumer
Date Mon, 13 Nov 2017 17:48:41 GMT
Hi, Hu,

Thanks for the KIP. Looks good overall. Could you document the mbean name
for the new metrics? We probably want the name to be consistent with
records-max-lag as described in
http://kafka.apache.org/documentation/#monitoring. Also, it seems that
records-lead-avg and records-lead-min don't need the partition prefix since
they are aggregates across all partitions. For records-lead, it seems that
it's better to add the topic partition as a tag, instead of as a prefix in
the metric name.
