Automatic notification file system getting full...

[Michael Francisco]

This is probably a no brainer, but I would like to setup a threshold level based on percent full that when reached causes the system to send out an email or a page. It seems that I'm receiving a message that the file system is full - probably from dmesg, but the system used to send an email when the file system reached 90% used -- that is until a consultant touched it...

TIA
Michael

Hi, try this script:
#!/usr/bin/sh

bdf | grep -iv filesystem | awk '{print $6 " "$5}' | while
read LINE; do
PERC=`echo $LINE | cut -d "%" -f1 | awk '{ print $2 }'`
if [[ $PERC -gt 90 ]]; then
echo "${PERC}% ALERT!" | mailx -s "${LINE} on `hostname` is almost full" root
fi
done

exit

Have cron fire it off every hour or so. Hope this helps.

Do the following



bdf | awk '{if ($5 > "90") print $NF,$5 }' > /tmp/test


This will create a file test in /tmp with the files sytems and the values of the usage. You can be creative in using this file as a form of mail , message etc . Run this as a part of script .

I use this one. It sends a page to a printer.

Wow! Almost instant response! I still haven't received response back from HP on our 24/7 4hr response time software contract...

Many thanks to all who replied

hi,
there's a very big difference in having 10% free on a 100MB filesystem or an a 100GB filesystem!! I think it would be a little bit more ideal to check on percentage combined with a check on effective free space.
just my 2 cents,
Thierry.

Here's another one that might help. We run it in the cron every fifteen minutes, but it will only e-mail you once an hour. Also, it checks off of the percentage and the value to exceed can easily be changed from 90 to 85 to 95, etc.

Good Luck.
