July 2026 (2026-07) highlights a key feature delivery in DataDog/integrations-core: Nutanix metrics tagging opt-in. Introduced an instance-level option to attach Nutanix resource extId values as tags on cluster, host, and VM infrastructure metrics, enabling granular correlation while keeping high-cardinality concerns in check by default (feature disabled by default). Implemented in commit 6eacfb6887a48841a3afc6da21f13b4e09db4cb9, with accompanying documentation updates (docs(nutanix): add changelog entry for #24303). This enhancement improves troubleshooting, incident analysis, and capacity planning by enabling precise mapping between metrics and Nutanix resources. No major bugs fixed this month; effort focused on feature delivery and observability improvements.
