There are 2 ways :-

1) ps -ef -o pcpu,user
This will show the amount of CPU usage "user" is using.

2) ps aux | head
Will show the top ten processes hogging CPU.

I do not know how to check for CPU utilization, but to check memory usage:  at a UNIX prompt, type dfspace and hit enter.  This will show how much free space is left on the disk.
