Metering based on consumed capacity
Keystone STaaS has metering based on the capacity consumed by you during your service usage.
Committed capacity is the capacity committed for a particular service level while purchasing the subscription. Consumed capacity is the capacity that your workloads actually use.
As a part of the Keystone service deployment, NetApp continuously monitors and measures the consumption of the service. At least once in every five minutes, a consumption record is generated by the system, detailing the current consumed capacity for your subscription. These records are aggregated over the billing period to generate invoices and usage reports.
