Looking for shell script to monitor CPU utilization and send mail once exceed 75%

Dear Group,

I'm look for shell script to Monitor CPU usage and send mail once it exceed 75% I'm running Suse10.4.

sorry bad post

How is checking the memory usage going to help you detect high CPU load?

use this for CPU usage:

if ! ps -e -o pcpu | awk '{c+=$1} END {if(c>75) exit 1;}'; then
  mailx -s "subject" -c "cc@user" "to@user" < emailbody
fi
