Developed a unified re-aggregation feature for the open-telemetry/opentelemetry-collector-contrib repository, standardizing metrics handling across disk, filesystem, and load scrapers within the hostmetricsreceiver. Leveraging Go for backend development, the work introduced configurable aggregation strategies such as sum, average, min, and max, all enabled through metadata-driven configuration and validation. The implementation included updates to metadata.yaml and automated code generation, ensuring that new aggregation attributes are consistently applied and validated. Comprehensive testing was performed using Go’s testing framework, with all tests passing, supporting more accurate and consistent observability while reducing manual validation effort in metrics aggregation workflows.

Mar 1, 2026March 2026 highlights: Implemented a Unified Re-aggregation feature across metrics scrapers in the hostmetricsreceiver (disk, filesystem, and load) to standardize and improve metrics handling. The feature enables configurable aggregation strategies (sum, average, min, max) and includes configuration and validation changes to enable reaggregation attributes via metadata.yaml, along with code-generation steps. This work supports more accurate, consistent observability and reduces manual validation effort. Verified reliability with a full test pass and code generation updates; aligned with the broader consolidation tracked in issues #46386, #46615, and related closes #46633, #46653, #46651.
