-------------------------------------
Summary: Differentiate metric latency measured in millis and nanos
Key: KAFKA-13243
URL: https://issues.apache.org/jira/browse/KAFKA-13243
Project: Kafka
Issue Type: Improvement
Components: metrics
Reporter: Guozhang Wang
Today most of the client latency metrics are measured in millis, and some in
nanos. For those measured in nanos we usually differentiate them by having a
`-ns` suffix in the metric names, e.g. `io-wait-time-ns-avg` and
`io-time-ns-avg`. But there are a few that we obviously forgot to follow this
pattern, e.g. `io-wait-time-total`: it is inconsistent where `avg` has `-ns`
suffix and `total` has not. I did a quick search and found just two of them:
* bufferpool-wait-time-total : bufferpool-wait-time-ns-total
* io-wait-time-total: io-wait-time-ns-total
We should change their name accordingly with the `-ns` suffix as well.
