Subject [GitHub] [zookeeper] hanm opened a new pull request #997: ZOOKEEPER-3439: Observability improvements on client / server connection close.

hanm opened a new pull request #997: ZOOKEEPER-3439: Observability improvements on client /
server connection close.
URL: https://github.com/apache/zookeeper/pull/997
 
 
   Currently when server closes a client connection there is not enough information recorded
(except few exception logs) which makes it hard to do postmortems. On the other side, having
a complete view of the aggregated connection closing reason will provide more signals based
on which we can better operate the clusters (e.g. predicate an incident might happen based
on the trending of the connection closing reasons).
   
   Server metrics was not added in this PR as we internally use a different metrics system
- so some work needed to migrate to ServerMetrics. Want to submit first to get community feedback
on this.
