ntop won't show you local processes usage.  It's a network monitor tool

Actually I'm wondering if he doesn't need to check into the app he installed
to see if it might be polling for something.  Polling can cause CPU usage to
peg, but does it in such a way that it usually doesn't impact other apps.

Hi,

I feel the best way to find out is

* stop all the processes see the top output
* start one service at a time and see the top output
* If you find that a particular service is using more system
resources
start monitoring the services.

Hello Every buddy

I'm checking another computer on the network. thats has an stranger 
behavior. Let me explain

This is a Linux/Debian computer installed some 9 days ago. 
Assigned user
want to run Moodle on it.
But they called me asking why with 40 users the server went to top 
processor and memory.
Hardware is a Sun-Ultra, with 2GB of RAM, and plenty of scsi
disk space...

The problem:
when I run "top" I have between 43% to 52% of processor used by
"Sys"> (System Tasks)
and I cannot identify what is taking these process power.
top does not give anything using the system nothing is being 
transfered (checked with iptraf) no disk usage (using iostat) no 
root kits, checked with ckrootkit some minutes ago no programs 
listening, checked with netstat

I don't know which tool can help me to find the problem.
I know there should be one and am surfing freshmeat.net, but I can 
happily accept any help you can give

Thanks in advance

Gabriel Orozco
