I have average and peak CPU utilization(in percentage) of a linux server with me . Mainly couple of web apps are deployed on the machine. I need to decide what AWS machine suits me based on that. AWS provides the machine costing based on CPU cores.
Now I need to find out the average and peak core utilization from CPU utilization , Can I deduce core utilization from CPU utilization based on some formula ? If not how can I find average and peak core utilization on linux server over a period of time ?
Are you talking about the system load averages? Like

If you do have that raw data just average the values to get the average and look for the highest value to get the peak? – Seth – 2018-09-25T06:37:28.687
Side note: AWS EC2 instance pricing is based on vCPU count, not core count. A vCPU is a hyperththread, not a physical core. The two are not identical, though probably close enough for your purposes. – Michael - sqlbot – 2018-09-25T11:26:32.037
