This thread has a great write up relevant for hyper-V. But it is very hyper-V specific. It does not address how to measure cpu steal on Win servers in EC2 and RS Cloud environments (I have tried the steps there, and they do not apply -- the counters are not available,and I have not spotted similar counters with diff names)
Question is: How do I measure it on win2008 and win2012 servers hosted on EC2 and Rackspace clouds?
I understand there may be no explicit answer to this question (e.g. a performance counter or such may not be available on Xen). So then interpret the question in a more meta manner: "How do I measure CPU Steal?" As there appears to be no explicit way to measure it, what is an effective implicit way?
Additional: Like on other cloud platforms, you can spin up 5 instances on rackspace cloud, and see wildly different performance on each. Because.... noisy neighbors.... so how to directly measure this, from a CPU and networking perspective?
