Usage is what we track directly, and then we apply the cloud provider's billing rules for the given service (e.g. S3) to calculate the resulting costs. So utilization rates for something like a Kubernetes cluster are easy to derive with the data already collected - just take the usage we've tracked and divide by the total resources available to the cluster. We haven't finished the k8s offering yet, but this would be a great feature / view for us to include (the same goes for most other compute offerings, e.g. EC2, ECS).

The same goes for on prem. We don't have any on prem customers currently, but it would be easy to add a feature where you input the total capacity and/or monthly cost of your on prem infrastructure, and use the collected usage data to calculate utilization rate and "effective cost" incurred by each feature, customer, etc. Thanks for the questions!
