During October 2025, zbqyexingkong developed RPC observability instrumentation for the alibaba/loongsuite-go-agent repository, focusing on enhancing monitoring and tracing for rpcx-go. They implemented both client and server instrumenters using Go, leveraging OpenTelemetry and gRPC to enable end-to-end tracing and metrics collection for RPC calls. Their work included updating dependencies in go.mod to ensure compatibility and maintainability, as well as removing unnecessary print statements to reduce log noise and improve production readiness. This feature improved the operability and performance visibility of RPC paths, providing a more robust foundation for backend observability and streamlined code for future development.
