Mar 1, 20252025-03 Monthly Summary for project-koku/koku: Implemented VM cost metrics model for VM count in the Koku reporting tool (constants, SQL for monthly/hourly costs, and model/accessor updates). Fixed a critical PVC creation path by gracefully handling IntegrityError in the ocppvc table, enhancing logging with cluster context, and adding a focused unit test. These changes deliver more accurate cost reporting, improved data reliability, and faster troubleshooting.
