You can have a clear view of all providers in Dubbo admin. Provider will remove it's info that consumers subscribe registry when it go offline,so does offline. How about taking a look at architecture description like this?

Just read info from registry. For instance , the default path is /dubbo in zk.

If i user nacos or other registery,can it also work?

Of course,it's a duty of the registry.
