**Issue** https://github.com/apache/dubbo/issues/15212 ### Description introduces a new command to the Dubbo QoS module: discovery-timeline. This command improves transparency into the service discovery process by listing active provider services along with their last known metadata update times and registry sources. It is designed to help developers and operators quickly inspect the current discovery state without diving deep into logs or complex diagnostics. ### Benefits 1. Providing a clear overview of all discovered services 2. Displaying when each service was last reported via metadata 3. Showing which registries are active and when they last refreshed 4. Diagnosing service visibility or registration issues 5. Monitoring refresh delays from registry sources 6. Validating service registration during application startup or scaling events ### Command Overview Command: `discovery-timeline` Used Examples: ``` discovery-timeline discovery-timeline service=DemoService discovery-timeline registry=zookeeper://localhost:2181 discovery-timeline page=2 limit=5 ``` **Output Example** ``` Discovery Timeline ------------------------------------------------------------ Registry |Last Refresh ------------------------------------------------------------ 127.0.0.1:2181 |Mon Jul 28 01:15:12 IST 2025 ------------------------------------------------------------ Provider Services Discovered: org.apache.dubbo.DemoService |Mon Jul 28 01:15:12 IST 2025 Discovered: org.apache.dubbo.MetadataService |Mon Jul 28 01:15:12 IST 2025 ------------------------------------------------------------ ``` **Tests Included** **Verified On** ``` $ telnet 127.0.0.1 22222 dubbo> discovery-timeline ``` -- This is an automated message from the Apache Git Service.
