[ale] Best command for cpu utilization

[mgm at atsga.com (Mike Millson)]

What is the best command to get cpu utilization? When I run iostat or
vmstat, it shows idle cpu at 14%. When I run top it initially shows idle cpu
at 5.7%, then changes to 98.0%.

Why does top show a low number initially then quickly display a new number
that is very different?

Why do top and iostat/vmstat show numbers that are so different?

Why do iostat and vmstat show numbers that don't add up to 100%?

Thank you,
Mike
