hachikuji commented on pull request #7551: KAFKA-9056; Inbound/outbound byte metrics should reflect partial sends/receives
URL: https://github.com/apache/kafka/pull/7551
 
 
   Currently we only record completed sends and receives in the selector metrics. If there is a disconnect in the middle of the respective operation, then it is not counted. The metrics will be more accurate if we take into account partial sends and receives.

> Currently the outbound byte metric is updated only after a `Send` is complete. If the client disconnects before completion, then the metric is not updated even if some of the data had been sent.
