Autoconfigures and runs the embedded gRPC server with @GRpcService-enabled beans as part of the spring-boot application. If you are using SpringBoot Dependency Management plugin, it might pull not the same version as the version this started was compiled against, causing binary incompatibility issue.
Spring Cloud Sleuth provides SpringBoot auto-configuration for distributed tracing. Sleuth configures everything you need to get started. This includes where trace data (spans) are reported to, how many traces to keep (sampling), if remote fields (baggage) are sent, and which libraries are traced. Add Spring Cloud Sleuth to the classpath of a SpringBoot application (together with a Tracer implementation) and you will see trace IDs in logs.
