File System Monitor Script

[hpuxrox]

Hi,

Im looking for a nice clean way to monitor file systems and if the file system exceeds a threshold of, lets say, 90% full, an email is sent out notifying me of the problem.

[Mark Grant]

This one allows different thresholds for different filesystems

You might need to tweak it a bit for your environment.

A configuration file looks like the following

default
warning=94
critical=95
rearm=59
actioned=unix

*/arch
actioned=database


# Follwing entry is to match datbase filesystems and not /usr
/u[0-9]*
warning=99
critical=99
actioned=database

/cdrom
warning=101
critical=101

Thanks, but im looking for something with no real hooks into anything like OVO. If it hooked in EMS, that would be ok, but Im looking for something that is very basic unix command level stuff that I can put in a cron job.

Hi,

This is a very simple script that can notify you if the filesystem reaches a certain threshold.

#!/usr/bin/ksh
LIMIT=90
STAMP=0
EMAIL=your_id@yourdomain.com

cleanup()
{
rm -f /tmp/fs$$ /tmp/fsreport$$
}

trap cleanup 0 1 2

for FS in $(df -l|awk '{print $1}')
do
USED=$(df -k $FS|awk '/allocation used/ {print $1}')
if [ $USED -ge $LIMIT ]
then
echo "$FS: $USED" >> /tmp/fs$$
STAMP=1
fi
done

if [ $STAMP = 1 ]
then
echo "Below are the Filesystems that exceeded the capacity\n\n" > /tmp/fsreport$$
cat /tmp/fs$$ >> /tmp/fsreport$$
mailx -s "Filesystem Warnings" $EMAIL < /tmp/fsreport$$
fi

Thanks Sridhar!! That was what I was looking for.

BTW: Are you still with PCS? Or are you the same Sridhar?

Yates,

The OVO thing is an option. If you don't do "-opc" then it alerts to your screen. You can then do whatever you like. However, I do appreciate that it's a bit old and craggy loooking now :)

Hey Yates!!!

Is that you?. Yeah I am the same Sridhar at the same place. How are you?.

Cheers,
Sri

Sridhar,

Doing good, yourself?

Brain still there? If so, tell him I said Hi.

Yeates,

Here's one I wrote that will check remote hosts from your local host. Just create a text file of the hosts you want to check and provide that file path to the script. You can modify it to send you email only if the filesystems are over 90%, or as I do, have it email me every day. Works with HP and Sun.

Regards,
Mark

If you want to do some nice monitoring, and can't afford OVO, have a look at Big Brother:

The disk monitoring is very customizable - you can set different thresholds for different filesystems.
