Does OpenstackSDK have support for usage metrics?

Question

So...I'm facing a problem which I need the available amount of resources (and how are they being used) in the DCs (focusing on each project/server/network consume) of my Openstack (Stein) through python code (cause the other functionalities are in python and I don't like mixing languages if it have support for a functionality).

Are there any support for this on OpenstackSDK libraries? If yes, where to find the API documentation (or code examples of usage). If don't, why?

You can use existing Nova APIs to list down Compute capabilities and available resources.

nova hypervisor-stats

+----------------------+-------+
| Property             | Value |
+----------------------+-------+
| count                | 2     |
| current_workload     | 0     |
| disk_available_least | 1378  |
| free_disk_gb         | 1606  |
| free_ram_mb          | 47003 |
| local_gb             | 1606  |
| local_gb_used        | 0     |
| memory_mb            | 48027 |
| memory_mb_used       | 1024  |
| running_vms          | 0     |
| vcpus                | 28    |
| vcpus_used           | 0     |

You can automate it by wrapping it in shell or calling python-openstack lib.
