cpu usage

cpu usage

[urgrue]

i have a server that continuously maxes out its cpu, and id like to try 
and pinpoint what is causing it.
the problem is, top shows for example:
CPU states:  0.7% user,  97.3% system,  0.0% nice, 0.0% idle

system is, presumably, kernel and kernel modules. but can i get any 
more detailed info about this kernel resource usage somehow?

If this is from /bin/top, system is a lot more than just kernel modules.
It includes every process run by root, and possibly a few others (such as
daemon or bin - not to sure about this tho).

Using top, you can also show what processes are using up the most CPU here
(my personal guess, without any access to further data, is that its a bad
daemon process).
