Cpu usage not working like explained in the readme.

Hi,

I have a 48CPU node, and it shows that in the exporter metrics :
pve_cpu_usage_limit{id="node/vc1"} 48.0

But if I stress the cpu with the stress commande, I have 25% in the proxmox webui and :

pve_cpu_usage_ratio{id="node/vc1"} 0.255540285174369

But the doc says :

# HELP pve_cpu_usage_ratio CPU usage (value between 0.0 and pve_cpu_usage_limit)

I am on pve 8.1.10.

So I think the truth is that the metric is just a "classic" percentage going from 0 to 1 and not from 0 to pve_cpu_usage_limit. If someone can confirm that ?

Thanks

Yes, I guess that the docs are wrong. A more accurate explanation is given on the API docs page.

• cpu: CPU utilization (when type in node,qemu,lxc).
• maxcpu: Number of available CPUs (when type in node,qemu,lxc).

We should probably just use the upstream descriptions. PR welcome.
