> In virtualized deployments of Geode some latency issues can be mapped back to the hypervisor not giving the guest enough cycles.   For this improvement, Geode will capture stolen time as presented by the OS in the /proc/stat file for Linux.  Steal time represents the time the virtual processor is waiting to be scheduled on the physical processor.
> Geode already monitors several CPU fields and Geode will be adding in support to capture  STEAL time.
