Linux: get wcpu from top

top -bn 1

Open in new window

This returns %CPU usage for each process.  How can I get the %WCPU usage instead?

You probably can't, without changing the code within "top".  I've only come across WCPU in the HPUX version of "top".

 ps -eo  "%c %C"

Open in new window

This returns:
COMMAND         %CPU
php                        10.0
sftp-server              5.0
ps                            3.0
bash                        1.0
Are you sure that is wcpu and not cpu?

Hmm, not sure it is either, really.  The man page says that %cpu is the total CPU time for the process since it started, divided by the time the process has been running.  This is different from the "top" values of %CPU (the time that a process is using the CPU in a particular period, e.g. 10 seconds, divided by that period) and %WCPU (as %CPU, but weighted by some method which I can't find described clearly).

All are approximations to some extent - is there a reason why you particularly wanted WCPU?

I want weighted CPU because it seems to give a better indication of processes that are have high CPU usage for longer than a very short burst.  

The values returned by your code seem to correspond to WCPU values anyway, so that is good.

Thanks!
