Scripting help...monitoring disk space..please

[asmpic]

Hi,
I stumbled upon a script on the internet that monitors disk space and if it reaches a certain percentage being full it send an email. However, the problem I encountered was that one of the file system names are longer than usual so it expends over to the other columns and causes the other data to be put onto a second line. So the script no longer works when this is the case. does anyone know how to fix the script to take this into account?

This is what I get when I run df-H. The first line goes onto a second line because of the file name so the script return incorrect information when I ask to print columns 5 and 1.

Filesystem             Size   Used  Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                        77G   8.2G    65G  12% /
/dev/sda1              104M    14M    86M  14% /boot
none                   525M      0   525M   0% /dev/shm

This is the script I'm using.

#!/bin/sh
df -H | grep -vE '^Filesystem|none|cdrom' | awk '{ print $5 " " $1 }' | while read output;
do
   #echo $output
   usep=$(echo $output | awk '{ print $1}' | cut -d'%' -f1  )
   partition=$(echo $output | awk '{ print $2 }' )
   if [ $usep -ge 10 ]; then
   echo "Running out of space \"$partition ($usep%)\" on $(hostname)" | mail -s "Alert: Almost out of disk space $usep" some@someone.net
fi
done

Try this:

df -H | grep -vE '^Filesystem|none|cdrom' | 
awk '
NF<5{getline}
$5>"10" && NF>5 {print "Running out of space "$1 " on "$5}'

I just tried your code, and it seems like it just skips the first line if it's too long. On my file system I have an Use% of 12, 14, and 0 but when I run your code I just get the second file system printed out: "Running out of space /dev/sda1 on 14%"
I would like it to determine that /dev/mapper/VolGroup00-LogVol00 and /dev/sda1 are low on disk space for this example...

Change 'df -H' to 'df -HP' and see if that helps.
