here is an hpux example for memory:

#!/usr/bin/ksh
while true ; do
mem=$(swapinfo | grep memory | awk '{ print $5 }' | awk '{ gsub(/[%]/,""); print }')

if [ ${mem} -ge 90 ]
then
echo Memory Usage too high ${mem}%
fi
done

Regards

First at all, 100% memory utilization is normal for linux because kernel uses RAM for caching/buffering.

Big Brother monitor and similar can alert (email, SMS) about certain events.
Ganglia and similar can graph CPU/memory usage.

Thanks for the response. i think i did not put my question in correct way.

Actually, i want to make my machine CPU and Memory Utilization to cross 90% is there any tool or script for this?

you can use some of these tools http://ltp.sourceforge.net/tooltable.php or just write a short program for allocating big amount of RAM
