Individual CPU usage not showing in ps/top
 

I'm experiencing a weird problem on several servers. They're all running as they're supposed to, but I can't see which processes are using cpu, a modified (removed some processnames) example from 'ps aux':
roboser 19503 0.0 0.0 2388 112 pts/0 S Aug13 0:00 /bin/sh SOMEPROCESS
roboser 19550 0.0 14.2 1440736 73408 pts/0 S Aug13 0:03 SOMEJAVAPROCESS
collect 7355 0.0 43.1 521500 221956 ? S 09:11 0:01 java -Xmn16m -Xms32m -Xmx256m -server -cp /usr/local/bin:/usr/local/c

As you can see, all cpu stats says 0.0, memory stats are working fine. I'm running 2.6.3, mixed mandrake and debian. The same problem occurs when I'm trying 'top'.

The servers are similar in hardware, running with a supermicro serverboard, p4 3ghz. I have no idea what can be causing this problem, so any pointers would be very helpful.

Thanks in advance.

try the command
mtop

'mtop' appears to be one of two things, a mysql monitor or a 'top' command for openmosix clusters - is there any special reason why I should use mtop? (does it use some different calculation method from /proc or something?)

Best regards,
