June 2025 performance highlights: Delivered observability and build stability improvements across two DataDog repositories. In DataDog/integrations-core, enabled export of historical disk usage metrics to Datadog, updated CI to emit metrics (uncompressed sizes, compressed sizes, and diffs), refactored dashboard creation to use a JSON template, and enhanced Datadog metric data handling. In DataDog/datadog-agent, fixed a build maintenance issue by excluding the win32com/test directory from test deletion to preserve integration tests.
