What about `ps aux` command? There is CPU% column... May be it fits you?

the explanation can be very easy!
imagine some tasks, which spawns a child process, which does some job and exits. Parent spawns another one and so on.
In this case CPU consumption is 100%, but top can't catch these processes (they work very little time and exit), so top doesn't
show you any processes consuming the 99% CPU Smile

An example of such situation is gcc compilation of some project. each file is compiled quite quickly.

AFAIR there was an option in top to show cumulitive process time. At least there was such an option in ps.

yes there is there a possibility , but in my case, i don't think,
because the load is very long (hours) , and yesterday, i have restarded a httpd, mysql on HN and strangely the load goes down. and nothing in top Sad
