Hi,

The following is the script which will send mail to admin if the server’s load is more than 15, please enable cron to execute it frequently.

#!/bin/bash
SUBJECT="`hostname`server load is high"
TO=admin@yourdomain.com
uptime > /tmp/load
if [ `uptime | awk '{ print$11 }' | cut -d. -f1` -gt 15 ];
then
mail -s "$SUBJECT" $TO < /tmp/load
exit
fi
