What's New?
Koku/Cost Management is now able to better report and distribute OpenShift storage costs, especially when running OpenShift on Azure. Enhancements for AWS, GCP and on-premise will follow.
Customers utilizing the Azure Disk CSI Driver storage class to dynamically provision persistent volumes, in conjunction with the latest release of the cost-management-metrics-operator, will now see improved correlation of Azure disk costs to OpenShift projects within the Azure filtered by OpenShift view. The latest operator enables us to collect the unique identifier for disks created by the CSI driver during the creation of persistent volumes.
For customers not using the latest operator, the previous method of matching persistent volume names to Azure disk resource identifiers will still be in use. However, this method can result in uncorrelated costs. We highly recommend adopting the new approach for optimal cost visibility.
Additionally, we've made significant improvements in assigning Azure disk costs to OpenShift projects. Through our extended efforts, we now map the capacity of Azure disks to the product name. This allows us to assign a portion of the disk cost based on the requested persistent volume capacity. The cost allocation is calculated using the following equation:
(Persistent volume capacity / Disk Capacity) * Cost of the Disk
The remaining unallocated portion of the disk cost has now been added under a new project called Storage unattributed. This project will now also include the cost of persistent volumes that have no persistent volume claims.
