Hello,
Thanks a lot, but I didn't find the proper way for this.
In CLI, I run *openstack hypervisor show hypervisor.domain.com http://hypervisor.domain.com*, it then shows all the needed information and data. I run *openstack service list*, I see this:

If I do understand your reply correctly, you mean I should run a single command for each server to find its free memory or CPU? For example if I have 100 servers, I should run 100 times a command with different server names?

Hi, Instead of Compute API, Placement is used for such statistics, see the API reference: https://docs.openstack.org/api-ref/placement/
You have to follow the resource providers on your compute, and resource providers can be in a tree with a root provider. For the available resources (resource classes) you have to list the resource provider inventories, and for the used resource you have to follow the allocations. Check the API ref and see the possibilities with CLI first perhaps. Be careful Placement API is microversioned like Compute API.
From python SDK you can find the relevant methods here:

Hello,
This is my python code:
import openstack
openstack.enable_logging(debug=False)
hypervisors = []
conn = openstack.connect(cloud='region1')
for hypervisor in conn.compute.hypervisors(details=True):
hypervisors.append(hypervisor.to_dict())I also run this:
for hypervisor in hypervisors:
print(hypervisor)This is the last result (other results are similar this):

As you see, values like *cpu_info*, *disk_available*, *local_disk_used* , *local_disk_size*, *local_disk_free*, *memory_used*, etc are *None*.
How can I have the following values? In the Openstack UI I see it says the free available disk, memory and CPU, but I don't know how to have them in python.
I see here https://docs.openstack.org/openstacksdk/latest/user/resources/compute/v2/hypervisor.html#openstack.compute.v2.hypervisor.Hypervisor.cpu_info the above values, but for me all are None.

Hello,
Thanks, but it seems my Openstack does not have this command.
[root@region1 ~]# openstack resource provider list openstack: 'resource provider list' is not an openstack command. See 'openstack --help'. Did you mean one of these? service create service delete service list service provider create service provider delete service provider list service provider set service provider show service set service show [root@region1 ~]# openstack --version openstack 5.3.1 [root@region1 ~]# openstack --help | grep -i resource bgpvpn create Create BGP VPN resource (python-neutronclient) bgpvpn delete Delete BGP VPN resource(s) (python-neutronclient) bgpvpn list List BGP VPN resources (python-neutronclient) network loggable resources list List supported loggable resources (python-neutronclient) project purge Clean resources associated with a project usage list List resource usage per project usage show Show resource usage for a single project
This is my output, and also my Openstack version.
