Performance Monitor Testing Script

[Brent W. Moll]

Does anyone have a script which will max out CPU to 100% then can be stopped?

We are testing out a product called Tivoli, which the company wants to use for system monitoring, and I want to run this on a test server to generate alarms in Tivoli.

Thank you :)

Hi
what Monitor in Tivoli do you use?
You can define several trigger values to create events in tivoli so why not sending events at cpu utilization of 0%?

Monitoring tool like Tivoli should have the flexibility of setting the threshold value for the parameter it is monitoring, just like HP's own suite of Openview applications. I don't see why you need to bring the CPU utilization up to 100% to test this.

Hi:

You can run one or more of something like this:

#!/usr/bin/sh
while true
do
let I=I+1
done

A Control_C will kill the script.

Hi Brent,

Find out you CPU clock speed :

# echo itick_per_tick/D|adb -k /stand/vmunix /dev/kmem
itick_per_tick:
itick_per_tick: 2360000

Then write a short C script that does no IO and set the loop ~= CPU ticks :

main()
{
int i;
int j = 0;

for(i=0;i<=236000000;i++)
j =+ i;
}

This should do the trick and will finish after a few seconds.

Cheers,

James.
