"Calculation of CPU Utilization" or "What Can be Simpler"?
A few days ago our testing team asked me how they could collect CPU utilization of our apps and then build cool plots based on that information. My answer was simple "Give me 15 minutes and I'll send you back a simple instruction or snippet". After 3 days of thinking and experiments I understood that I knew absolutely nothing about CPU Time utilization, how to calculate it and what it means. Anyway, I have received quite interesting results and ready to share them.
