[Question] <title>Add monitoring grouping function

### Question

多台主机需要监控的情况下，不支持分组，无法区分项目，有些乱，是否考虑监控主机支持分组

The issue requests grouping monitored hosts so multiple projects can be distinguished, but names no files, tests, entry points, or acceptance criteria. Start by locating the host-monitoring management area and clarify how groups should be created, assigned, and displayed. Done should mean hosts can be separated into meaningful project groups without ambiguity.
