Linux CPU

I am running RHEL 6.2

My machine usually shows about 100 percent idle

It is now running at 96 percent idle, and it is doing this somewhat persistently

How do I find out what is taking the 4 percent ?  What commands should I run

Run this command,

ps -eo pcpu,pid,user,args | sort -r -k1 | less

It gives you which process takes the highest CPU cycles in descending order.
