> High CPU deviation (100-400%) is seen in the metrics view. The regression was caused
becase HostStats returns CPU usage in percentage and memory usage in bytes, while the deviation
calculation method did not assume that passed values are in percentage and multiples the ratios
by 100 resulting in 100x the actual values.
