Top command


If this has been answered somewhere my apologies, I could not locate it.
In any case when running the "top" command one of the lines is

Cpu(s): 0.3% us, 0.7% sy, 0.0% ni, 0.0% id, 98.7% wa, 0.3% hi, 0.0% si

What is the wa field? (I hope it means waiting). Mine seems to be too high?

My guess is us is user, sy is system, ni ? id ? , hi ? si?

again, my apologies if this is answered elsewhere. I thought I would find it in man, but I had no luck seeing it there either.

Thanks,

Paul

I believe it goes something like this -

wa = wiating for IO
us = userspace
sy = system/kernel
ni = nice processs
id = idle
hi = hardware interrupts
si = software interrupts

I dont get the "nice processes" means, although i know that "nice" is a command to set the process priority.

Could you please explain this item a little detail? Thx in adv
