If only worried if its near capacity, something like:

#!/bin/bash

threshold=90

for i in $(df |grep -v Filesystem |sed 's/.* \([0-9][0-9]\?\)%.*/\1/g'); do 
     [ $i -gt $threshold ] && callnow=true
done

[ $callnow ] && df | mail -s DiskAlert 5555555555 at somecell.net

#

would work. Probably a good thing to do though is create a lockfile so
it doesn't keep sending messages every few minutes, or however you run
it from cron:

lockfile=/tmp/$(basename $0).lock
[ -f $lockfile ] && exit 

Just remember to remove the lockfile.

You can do similar things with temperatures and other system
components.
