Sending mail when partition is full 1

[Jimbo2112]

Hi All,

I am writing a script to alert me of when the /dmps partition on my server is above 90% full. I need to know the command sequence to get my Unix system to mail a message to my general mail account

e.g. me@my.domain.com

The mail message need only contain the subject matter which is held as a very small text file created from the small script that I have writen so far.

I am sure this is posible but my faithful old Unix in a Nutshell book has left me scratching my head!

Any ideas?

Cheers

Jimbo

Look at the script on the unix scripting forum FAQ.

Not sure if this helps, but you could just add something like this:

if condition is met
then

cat message.file | mailx youremail@domain.com

This is what I use:

EMAIL=`cat /usr/local/cfg/email_bkup.txt`
hostnm=`hostname`

diskstat=`df -k | grep dsk | awk '{t = $2; u = $3; a = $4; p = $6} { if ((u/t*100) > 93) printf("File System FULL Alert: %-15s\t %8d MB Free\t %5.3f%%\n",p,a/1024,(u/t)*100) }'`

if [ "$1" = "mail" ]; then
echo "$hostnm \n$diskstat" | mailx -s "${hostnm} File System ALERT!!" ${EMAIL}
echo "$hostnm \n$diskstat"
else
echo "$hostnm \n$diskstat"
fi

Hope this helps.

Thanks all,

I think the crucial thing here is the `mailx` command. I have integrated this into my script and tried it out with a purposely low limit to make the mail send the message. I did this about 10 minutes ago and have not received anything yet.

I am wondering if my system might not be set up to send external mail. How can I check this?

Cheers

try this...

df -k | grep -v capacity | while read dsk
do
size=`echo ${dsk} |awk '{print $5}' | sed 's/%//'`

if test ${size} -ge 90
then
mailx -s &quot;FS SIZE LIMIT&quot; yourmail@domain.com <<EOF
echo ${dsk}
EOF
fi
done

I use this script is works a treat. Feel free to use and amend. england for the cup !
