January 2026 monthly summary for the DataDog/datadog-agent repo focused on stabilizing the host-profiler, improving configuration reliability, and accelerating developer workflows. Deliverables targeted reliability, configurability, and testability with measurable impact on uptime and deployment consistency. Key features delivered: - Datadog internal fork upgrade for ebpf-profiler: Replaced upstream ebpf dependency with Datadog's internal fork to improve reliability and reduce dependency churn. (Commit: cb4b384ccec5a41726e81d3678c3cde150dca278) - Host profiler configuration enforcement and normalization: Introduced mechanism to enforce correct defaults and prevent misconfigurations across agent and standalone modes. Added converters to validate and normalize configurations (processors, receivers, exporters); improved error handling and expanded test coverage. (Commit: 500dcf3399a64614b40c2d6e074fdeab3f262258) - Containerized deployment and development workflow for host-profiler: Added docker-compose setup, Dockerfile, entrypoint, and launch scripts to run host-profiler in a container, enabling access to container attributes and addressing host limitations. In-container configuration overrides supported for local builds and manual profiler starts. (Commits: ea4045b47b1d3e88c551eddb939e0bc3b222ca15; 27e834d9f4b307f27d7dfa8f344f2b382d7205d5) - Testing workflow for host-profiler converters (golden files): Introduced a mechanism to update golden test files for host-profiler converters to simplify updates as features evolve. (Commit: 5427ecd77bfb8b72e074876e9cead1790f07804a) Major bugs fixed: - None explicitly reported in this period; the work focused on reliability improvements, configuration correctness, and developer workflow enhancements that reduce misconfigurations and streamline testing. Overall impact and accomplishments: - Significantly improved reliability and stability of the host-profiler by replacing dependencies, validating configurations, and hardening default behaviors across deployment modes. - Enhanced developer experience and CI/test velocity via containerized development workflows and golden-file based testing. - Improved cross-component configurability, test coverage, and traceability with clear commit references. Technologies/skills demonstrated: - Containerization with Docker and docker-compose; in-container overrides and local build support. - Configuration validation and normalization patterns for multi-mode deployments. - Test automation, golden-file testing, and contributor-focused tooling. - End-to-end traceability from feature work to commits to production behaviors.

December 2025 monthly summary focused on delivering features and stability improvements across two repositories: Shopify/opentelemetry-ebpf-profiler and DataDog/datadog-agent. Delivered key capabilities for observability, symbolication, and configuration reliability, with measurable business impact.
