February 2026 monthly summary for DataDog/integrations-core: Delivered granular Elasticsearch shard metrics by tagging elasticsearch.shards with prirep and index, enabling detailed shard placement visibility and improved observability. Included config updates, tests, and changelog fragments, code quality improvements (ruff formatting), and CI-aligned changes. Work was co-authored with Ilia Kurenkov and aligns tag naming with existing metrics. This delivers better capacity planning, faster troubleshooting, and more accurate alerting for Elasticsearch deployments.
