In June 2025, Mohammad Ramezani enhanced network telemetry in the microsoft/sonic-gnmi-dev repository by delivering two features focused on watermark observability. He implemented queue-level periodic watermark telemetry, exposing SAI queue statistics through PERIODIC_WATERMARKS and enabling queries by queue name. Additionally, he introduced virtual paths for periodic priority group watermarks, allowing port-name-based queries via OID-name resolution. These updates, developed in Go and leveraging gRPC, improved the system’s ability to monitor and diagnose watermark-related issues. Mohammad also updated documentation and tests, ensuring robust coverage and supporting data-driven capacity planning for more reliable network operations and faster troubleshooting.

June 2025: Delivered two telemetry enhancements in microsoft/sonic-gnmi-dev that strengthen observability and queryability of watermark metrics. Implemented queue-level periodic watermark telemetry exposed via PERIODIC_WATERMARKS and added virtual paths for periodic priority group watermarks, enabling port-name-based querying and easier capacity planning. Updated documentation and tests to reflect the new functionality. These changes improve troubleshooting speed, reduce mean time to detect and diagnose watermark-related issues, and support data-driven capacity planning. Technologies demonstrated include SAI queue stats, PERIODIC_WATERMARKS, virtual path mappings, and OID-name resolution.
