Hi all
I think that we are all (people working with ceilometer), trying to figure out how to get the system actual data metrics from VMs.Do we need to install Healthnmon in order to get them? (because ceilometer as Julien already said, can't do it yet)
Cheers

If you know how to retrieve the actual memory or disk used (rather than
allocated) by a VM by measuring from outside the VM, please enlighten
us. We (Ceilometer) don't know how to do that, that's why we don't do
it actually.
