hi i'm reaching out for help understanding meter values across hypervisors.
for context, we have an open bug in Ceilometer where the value used to capture cputime of an instance is being reset whenever the instance is restarted or shutdown[1]. this seems to be the expected behaviour for libvirt driver[2] but it conflicts with the fact that the meter is currently defined as 'cumulative' -- which by definition, should not reset. it seems the correct meter type is a 'gauge'.
with that said, for other hypervisors: vmware, Xen, hyper-v, etc... does cputime also reset when an instance restarts/shuts down? is there a way to find a truly cumulative value for cputime for libvirt and other hypervisors that reset?
