Dev Hingu commented on HBASE-29289:
-----------------------------------
As per the suggestion from [~wchevreuil], we have decided to use the existing
metrics subsystem for tracking and reporting these info.
I used
[ClientMetrics|https://github.com/apache/hbase/blob/f36a1cf3269264cd225b7820aee15da7cb0214ad/hbase-protocol-shaded/src/main/protobuf/server/ClusterStatus.proto#L203]
from ClusterStatus.proto to include these new fields and used existing
framework of MetricsUserAggregateImpl, MetricsUserSourceImpl to transfer these
metrics periodically from RegionServers to Master.
I've already raised a PR with this logic and added these new fields into hbtop
client view as well.

> The hmaster page can display as follows, so that the cluster admin can easily
> get the client info such as username/version/ip/socketNum and so on, the
> socketNum is aggregated by the previous info columns.

> When the client requests to establish a connection with the HRegionServer,
> the request header contains the client user/version information.
> HRegionServer will maintain a channel connection with the client, which is
> managed in NettyRpcServer. we can save the client attribute information of
> each Channel, and regularly collect statistics on the attributes of all
> channels.
> HRegionServer can report the information to HMaster through HMaster's
> RegionServerReport api.
