March 2026 — Apache Dubbo instrumentation delivered in the open-telemetry/opentelemetry-java-instrumentation repository, focusing on stable semantic conventions and telemetry metrics updates. Key accomplishments include introducing stable semconv for Apache Dubbo, improving RPC attribute handling, and expanding test coverage to ensure conformance with the new semantics. Metrics emitted by the Dubbo instrument were updated to align with the updated semantic standards, improving observability consistency across OpenTelemetry instrumentation. There were no major bugs fixed this month; the work centers on feature delivery with a stronger baseline for future reliability. Business impact: improved interoperability for Dubbo-based services, clearer telemetry signals, and reduced risk for downstream consumers due to standardized semconv and metrics. Technologies demonstrated: Java instrumentation, semantic conventions (semconv), RPC attribute modeling, test-driven validation, and metrics emission alignment.

April 2025 monthly summary focusing on delivering reliable telemetry and enhanced observability across OpenTelemetry Java Instrumentation and semantic conventions. Key work delivered includes a Dubbo instrumentation ordering fix to prevent conflicts by forcing OpenTelemetry filters to run before user-defined filters (default order -1), applied consistently to the agent and library-autoconfigure modules for Dubbo 2.7. In addition, JVM GC metrics were enhanced with a GC cause attribute to enable deeper performance analysis. The semantic conventions were updated to introduce an optional jvm.gc.cause attribute, standardizing observability across metrics. Documentation and configuration were updated to support opt-in usage and a new system property for GC cause reporting. These changes collectively improve data quality, diagnosability, and actionable insight for performance tuning while maintaining compatibility with existing deployments.
