  15. +-----------------------------------------+-----------------+

This command lists the services provided and consumed by Dubbo, as well as the number of addresses for the consumed services.

Note

  • Services prefixed with DubboInternal are built-in services of Dubbo and are not registered with the registry by default.
  • The first part of the service publishing status nacos-A(Y) represents the corresponding registry name, the second part represents the registration model (A stands for application-level address registration, I stands for interface-level address registration), and the third part indicates whether the corresponding model is registered.
  • The first part of the service subscription status nacos-AF(I-2,A-2) represents the corresponding registry name, the second part represents the subscription model (AF stands for dual subscription mode, FA stands for application-level subscription only, FI stands for interface-level subscription only), the first half of the third part represents the address mode source (A stands for application-level addresses, I stands for interface-level addresses), and the second half represents the corresponding number of addresses.
