Adjust CPU graphs based on CPU ratio limit

[DANILO MONTAGNA]

Hi,

When we define resources limits on CPU usage, example: 2 vcpu with CPU limit of 1.0 (50%) the VM CPU usage graphs only goes to 50% maximum, but the VM is using 100% of the resources available because of the ratio limit imposed at this VM.

Is possible to adjust the graphs based on CPU limit instead of CPU count? or instead of graphing based on % usage, we could choose MHz usage!!

No. The graph will scale anyhow with the first average/max value above the CPU limit. And from the logic, the KVM process can use 2 CPUs (cores) but the VM inside can only use one (limit).

or instead of graphing based on % usage, we could choose MHz usage!!

This is better done by an external monitoring system.

which one do you recommend, without the need of installing an agent on guest side?
