March 2026 monthly summary for DataDog/datadog-agent focused on ARM64 platform expansion for Host-Profiler. Delivered ARM64 build support by migrating Host-Profiler to a multiplatform base image, enabling builds and runtime on ARM64 architectures. This work broadens deployment options, reduces manual work for ARM64 customers, and strengthens the agent’s cross-architecture capabilities.

February 2026 monthly summary for DataDog/datadog-agent. Focused on consolidating host-profiler symbol upload functionality within the agent to reduce external dependencies, improve stability, and streamline maintenance. Delivered the Embedded Symbol Uploader directly in the datadog-agent repo by removing the dd-otel-host-profiler dependency and integrating the symbol uploader code under comp/host-profiler/symboluploader. Validated end-to-end by running the profiler and confirming symbol file uploads are successful, ensuring continued development parity with opentelemetry-ebpf-profiler.

Month: 2025-11 — Delivered two cross-repo enhancements that improve observability and runtime efficiency. Implemented OpenTelemetry (OTEL) context mapping for Linux in DataDog/dd-trace-go to enable external processes to access tracing context, and optimized memory usage in grafana/opentelemetry-ebpf-profiler by refining trace frame allocation and removing redundant frame cloning. These changes reduce cross-process latency in tracing workflows and lower memory footprint for high-cardinality tracing workloads, contributing to better production observability and profiler performance. Technologies demonstrated include OTEL, Linux anonymous mappings, cross-process tracing, memory optimization, and performance profiling. Business impact includes improved observability, reduced resource usage, and faster trace insights.

Month: 2025-09 — Focused on stability, accuracy, and broader PIE compatibility for Shopify/opentelemetry-ebpf-profiler. Delivered two core items: a bug fix improving logging for invalid Ruby strings to prevent panics and to enrich error diagnostics; a feature enhancing TLS offset retrieval for PIE Go binaries, with new test binaries and improved assembly decoding across AMD64/ARM64, ensuring accurate Go label collection regardless of build mode. These changes reduce troubleshooting time, widen platform support, and improve profiling reliability. Technologies demonstrated include Go binary analysis, PIE-aware assembly decoding, enhanced logging, and test infrastructure. Impact: improved runtime stability, broader compatibility, and better business value through more reliable performance data and faster issue diagnosis.

June 2025 monthly summary for DataDog/datadog-ci: Fixed a regression in ELF symbol handling that affected symcache generation and implemented a preservation strategy for essential dynamic symbol table sections when using --only-keep-debug. Refactored the symbol extraction to maintain critical sections and ensure reliable symbol caching for ELF binaries, aligning with ongoing efforts to improve build performance and debugging reliability.
