  • Naming convention
  • Attributes
  • Example

If you are using automatic instrumentation, RPC call spans are created and attributes filled automatically. If using manual instrumentation, follow the conventions described below:

Naming conventionNaming convention

The span name has the <package>.<service>/<method> format, e.g., grpc.users.UserService/GetUserInfo. If the package name is missing or unknown, the <package>. part is omitted. For more information, see the RPC span naming specification.
