For a quick view, mpstat will give you individual CPUs. For monitoring, pinga123 is correct; sar is the answer unless you want to roll your own. I use a custom rrdtool script for my purposes.

Thank you all for your replies but i got it solved using top.

Just run top and press numeric 1 and you get core wise cpu utilization.
