I can see an argument for an overall CPU (and ram) use sparkgraph at the 
host level, but on a per-VM basis I would expect it to show a percentage 
of what is available to that VM. If you have more than a few cores on 
the host the CPU graphs become useless as they can only show a couple of 
pixels of variation.

Would be great to get a per-vm memory utilisation chart, is the data for 
that exposed? If someone can point me in the direction of the data for 
that I will have a go at adding it.
