26/// Usage reports (os-simple-tenant-usage)
27///
28/// Reports usage statistics of compute and storage resources periodically for an individual tenant
29/// or all tenants. The usage statistics will include all instances’ CPU, memory and local disk
30/// during a specific period.
31///
32/// **Warning**
33///
34/// The os-simple-tenant-usage will report usage statistics based on the latest flavor that is
35/// configured in the virtual machine (VM), and ignoring stop, pause, and other events that might
36/// have happened with the VM. Therefore, it uses the time the VM existed in the cloud environment
37/// to execute the usage accounting.
38///
39/// More information can be found at
40/// http://eavesdrop.openstack.org/meetings/nova/2020/nova.2020-12-03-16.00.log.txt, and
41/// https://review.opendev.org/c/openstack/nova/+/711113
42///
43/// Microversion 2.40 added pagination (and next links) to the usage statistics via optional limit
44/// and marker query parameters. If limit isn’t provided, the configurable max_limit will be used
45/// which currently defaults to 1000. Older microversions will not accept these new paging query
46/// parameters, but they will start to silently limit by max_limit.
47///
48/// ```text
49///   /os-simple-tenant-usage?limit={limit}&marker={instance_uuid}
50///   /os-simple-tenant-usage/{tenant_id}?limit={limit}&marker={instance_uuid}
51/// ```
52///
53/// **Note**
54///
55/// A tenant’s usage statistics may span multiple pages when the number of instances exceeds limit,
56/// and API consumers will need to stitch together the aggregate results if they still want totals
57/// for all instances in a specific time window, grouped by tenant.
