Off the top of my head - totally untested, not even syntax checked.
#The name of the server
NAME=`hostname`
# Maximum load you want to allow
MY_THRESHOLD="0.5"
# of seconds to wait between load checks.
SECONDS=5
# Loop almost forever.
while (`true`) ; do
# Replace $1 with which ever field of loadavg you want.
load=`cat /proc/loadavg | awk '{print $1}'`
if [ $load -gt $#MY_THRESHOLD ] ; then
mail -s "$NAME $MY_THRESHOLD" [EMAIL PROTECTED]
# If we stay in this loop you'll get a TON of emails
on your cell phone.
exit
fi
sleep $SECONDS
done
