view multi-core or mlti-cpu utlization on linux

Question

I have a program running on Linux and I need to determine how it is utilizing all the CPUs/cores. Is there any program for viewing this information?

Answer 1

Run the 'top' command and press '1' to see the individual core is the best way to see the cpu cores usage .. another option is run cmd- cat /proc/stat to see the cpu cores usage
