The tools described above help you manage those resources, especially the CPU resource: nice is a great tool for 'one off' tweaks to a system. lie to us! Run the command like this: /usr/local/bin/matho-primes 0 9999999999 > /dev/null & This will generate a list of prime numbers from zero to nine billion nine hundred ninety-nine million nine hundred ninety-nine bursts of CPU usage: how can I find out which processes are the cause?

The total CPU utilization of the system: Figure 1: The system overview section at netdata, just a few seconds after the command was run And now, the applications netdata believes are Now start another matho-primes process in the cpulimited group: sudo cgexec -g cpu:cpulimited /usr/local/bin/matho-primes 0 9999999999 > /dev/null & Observe how the CPU is still being proportioned in a 2:1 ratio. It makes my life much easier. Yes, I know what you think.

Check out the great answers to Calculating CPU usage of a process in Linux which explain how to calculate CPU usage % for a single processor. It would be nice if I could do this using Performance Monitor, but I am open to alternative solutions as well.
