You don't mention which version of software you're using, but with 6.x it shows a bunch of statistics including CPU. You have to "page" through them.

# show statistics host

Memory Usage

CPU Statistics

Usage over last 5 seconds = 44

Usage over last minute = 36

I don't know if this method is supported

by Cisco TAC but you can do it quite easily.

I tested this on version 4.1. By the way,

IDS version 4.1 is a LinuxOS.

a- create an account called "test" and assign "service" privilege,

b- logout of the IDS and log back in with

the test account. This will put you in

bash shell,

c- type "su -" and enter the "admin" or "root" password,

d- now you are in superuser mode, type "top".

This will show you cpu usage in real-time.

Thanks a lot..It is working..but its is showing separatly like bellow..What is the meaning of nice in to know the total cpu usage i have to add the all usages apart from idle usage..

CPU states: 18.4% user, 3.7% system, 3.1% nice, 74.7% idle

How familiar with Unix/Linux? That's how

it works. Another command you may want

to use is "vmstat x" where x is the number

of seconds you want it to repeat.
