Microservices Engine (MSE) ZooKeeper instances serve as the registry for Dubbo services. After your Dubbo services register with an MSE ZooKeeper instance, you can view the service list, inspect provider details such as IP addresses and group names, and check subscriber connections from the MSE console.
Each registered service has two views:
Providers: The instances that expose the service.
Subscribers: The instances that consume the service.
