Electricity consumption not shown on Ubuntu KVM about scaphandre

[bpetit]

Hi,

Did you follow this procedure ? https://hubblo-org.github.io/scaphandre-documentation/how-to_guides/propagate-metrics-hypervisor-to-vm_qemu-kvm.html

Do you have a working scaphandre with qemu exporter on the physical machine ?

Without this it wont work as we need real rapl metrics from the host to be transmited to the agent inside the vm.

Would be interesting to see how powertop estimates energy in this context though

As far as I understand this method for domain owners, I have only a few virtual machines, I have no access to the domain. Please correct me if I'm wrong

You're right, it's made for bare metal machine owners / private cloud staff / ...

Scaphandre doesn't provide (yet) a mean to evaluate the power usage on a virtual machine without gathering metrics from the bare metal host first.
