I think the pollster implementation can be done. I wouldn't implement
this in the compute agent, but probably in some hardware agent, because
it's likely it would be used in different kinds of environment and not
only on compute node, i.e. you may also want to meter hardware usage for
you cinder or glance node anyway.

About the 10 minutes polling interval Doug mentionned, this can be a
problem indeed, but it's still solvable later and would be easy to solve
if this in a different agent, since you could change the periodic
interval for pollster runs to something like 1 or 5 minutes.
