I can use top to see the overall cpu utilization in the system but i m using a system with 24 cores .How would i monitor each core utilization ?

The system is used as Oracle VM Server for Virtualization.

# uname -r

Hi,

Is using the 1 option in top what you are looking for?

Code:

Toggle SMP view: '1' single/separate states;

Hope this helps.

You may try to htop for a visual representation of the CPUs usage. It runs inside a terminal, as well.
