suggestions, [~adoroszlai] [~sumitagrawal].
> Improve SCM related thread prefix names
> ---------------------------------------
>
> Key: HDDS-10083
> URL: https://issues.apache.org/jira/browse/HDDS-10083
> Project: Apache Ozone
> Issue Type: Improvement
> Components: SCM
> Affects Versions: 1.3.0
> Reporter: JiangHua Zhu
> Assignee: JiangHua Zhu
> Priority: Major
>
> When the SCM service is running, many threads use the same prefix name. The
> prefix name here directly uses scmUuid. The advantage is that it is easy to
> identify.
> scmUuid: bc228776-c5ab-5eb5-c35c-3b157cc13381
> But a new problem will arise, that is, the thread name is too long.
> Here are some basic logs:
> {code:java}

> The length of scmUuid here reaches 36 bits.
> I think the prefix name here should be reduced, such as using ip+port, which
> will be much smaller.
> for example:
> Thread prefix name: bc228776-172.10.10.56-9894
> new logs:
> {code:java}
> 2024-01-04 16:05:57,930 [bc228776-172.10.10.56-9894-server-thread470] INFO
> org.apache.ratis.server.raftlog.segmented.SegmentedRaftLogWorker:
> bc228776-172.10.10.56-9894@group-5B5552266EB7-SegmentedRaftLogWorker: Rolling
> segment log-60086216_60119685 to index:60119685
> {code}
> I think such improvements are beneficial.
