Worked on the grafana/opentelemetry-ebpf-instrumentation repository to deliver HotSpot JVM memory metrics integration, enabling collection of heap summary and memory pool GC metrics through GCTracer uprobes and USDT probes. Leveraged Go programming and eBPF to unify Go and JVM runtime metrics via a shared event-driven architecture, reducing duplication and improving exporter integration. Enhanced reliability by stabilizing USDT metrics against kernel verifier constraints and cleaning up IP-map keys to prevent stale mappings. Updated BPF map and header organization for maintainability, improved cross-architecture compatibility, and strengthened CI/test automation, resulting in a more robust and extensible backend performance monitoring pipeline.
June 2026 monthly summary for grafana/opentelemetry-ebpf-instrumentation: Key features delivered include HotSpot JVM memory metrics via GCTracer uprobes and USDT probes, enabling heap summary and memory-pool GC metrics in the JVM metrics pipeline, with improved USDT handling for performance and reliability. Architecture/process improvements include routing Go and JVM runtime metrics through a unified shared event path and consolidating runtime metric dispatch. Major bug fixes include stabilizing HotSpot USDT metrics, ensuring compatibility with kernel verifier across versions, and cleaning up USDT IP-map keys on close to prevent stale mappings. Other fixes cover BPF map header restructuring for clang-tidy safety and CI/test stabilizations. Overall impact: enhanced observability, reliability, and maintainability, paving the way for more robust exporters and multi-arch support. Technologies demonstrated: eBPF, GCTracer uprobes, USDT probes, BPF maps, Go tooling, clang-tidy, CI/test automation.
