script for file system alert

gab_in — Wed, 25 Feb 2009 09:28:22 GMT

Hi,

Do you have any script which I can use on RedHat Linux system to get the e-mail notification, once the file system reaches the threshhold limit (e.g. /opt is 97%).

Thanks in advance
Gab

Its a HP-UX thread but the code will work for Linux.

If you're running an HP Proliant server, the Proliant Support Pack (more specifically, the System Management Homepage) supports filesystem threshold notifications:

Note: It by default sends the email to 'root' on the local system. I typically just setup an alias to my email address for root in /etc/aliases for sendmail.

If you just want something that is a simple notifier,

#!/bin/bash
threshold="85"
used=$(df -h $1 | grep "\%" | awk '{print $5}' | sed -e "s/\%//)
[ $used -lt $threshold ] || mail -s blahblah and all the other things you want to do

Something like that would do (untested thou) I believe. This looks at the procentages the device supplied.
Usage is, ./script.sh /home

I would use some other program to handle this thou, should be alot of programs out there able to do this. Maybe Cacti or Nagios would be an idea depending on how big your environment is.
