See Nagios or such tool, or just parse the output of a
df -k
or
df - h

It's not quite what you're asking for - but I mail myself this every morning...

----< script start> -------------------
#!/bin/ksh
disk_ck()
{
echo "\n DISK SYSTEMS"
echo " ------------\n"
echo " Disk Utilization sorted by percent utilization"
echo " - - - - - - - - - - - - - - - - - - - - - - - "
export stat_tmp="/var/tmp/statck.disk.$$"
bdf > $stat_tmp
head -1 $stat_tmp
grep -v ^Filesystem $stat_tmp | sort -k 5

echo "\n Disks Over 90% Full "
echo " - - - - - - - - - - "
integer FULLCT=`grep -v ^Filesystem $stat_tmp | \
grep -e "9.%" -e "1..%" | sort -k 5 | wc -l `
if [ $FULLCT -gt 0 ]
then
head -1 $stat_tmp
grep -v ^Filesystem $stat_tmp | grep -e "9.%" -e "1..%" | sort -k 5
else
echo " ... No filesystems found over 90 percent full"
fi
rm $stat_tmp
}

disk_ck | sendmail imv@xyz.org

--- < script end >----------------------

You could make a few changes to this to send mail only when needed. Send all of the output to a tmp file, and use the last "if else" statement above as a basis of whether or not to use sendmail at that point in the execution to send and email to you.

Well Maaz, I just realized that script I put is for HPUX, not Linux, because it uses "bdf" instead of "df". You'd have to do some work to make it work in Linux. Sorry about the posting error.
