How to identify which processes consume most CPU?
I want to have a list of top consumption in a range of time, or at least when the total CPU consumption is over a threshold. On many task managers, sorting the processes by CPU only show which ones use most in real time.
In Resource Monitor, I click around but see nothing suits my need:
In System Informer, the "CPU history" helps seeing which processes take how much CPU at the moment, so it does help. But in my case, you can see that there is a huge drop on the system idle process, but there is no process being responsible for the consumption. Perhaps they were killed quickly. I need a longer log so I can examine better
`
You can examine a longer history, but I don't know how to read it. In the graph below, is it correct that the process in the tooltip is the one take most CPU at the moment? Because as you can see, firefox only takes up 15%. I don't know what goes to the rest. I don't know what the colors mean.
