Hi,

This is the script which alert you when file system is upper then 90% or full

bdf|grep -v File |awk '{ if ( $(NF-1) > 90 || $(NF-1) == "100%" ) print}'

you can make a script file then make it in cronjob to check it frequently.

Waiting UNTIL a filesystem is full is Foolish and Dangerous. You need to be PRO-Active before a filesystem fills up, unless you enjoy potentially lost and corrupt data.

Change that script to alert when an FS reaches anywhere from 80%-94%, especially when an FS is SMALL. The larger the FS, then the more room to grow into, thus you might be able to increase the % to a larger number before alerting. There is NO magic bullet.

Additionally you need to PLOT your FS usage and be prepared to add additional storage if necessary.

You can use bdf and mailx command to do this. And as said by olympian have the upper limit of f/s in the range of 90-95%.

Make the Execution of this script with cron schedular.

#!/bin/ksh
# Alerter
for line in `bdf | awk '!/^Filesystem/ { print $5" "$6 }'`
do

per=$(echo $line | awk '{ print $1 }'
fs=$(echo $line | awk '{ print $1 }'

per1=$(echo $per | cut -d'%' -f1)

if [[ $per1 -gt 90 ]]
then

echo "$fs is greater than 90%" | mailx -s "Alert"

fi

done

HTH.

Change
per=$(echo $line | awk '{ print $1 }'
fs=$(echo $line | awk '{ print $1 }'

to
per=$(echo $line | awk '{ print $1 }'
fs=$(echo $line | awk '{ print $2 }'

ok.

I have two shell scripts. One returns free space percentage.

free.sh 5 will return filesystem that have less the 5% free space.
or
free.sh 20 will return filesystem that have less than 20% free space

The following snippet runs from cron,
you can easily modify to send page

SPACEWARN=20

for arg in $(free.sh ${SPACEWARN}|cut -f1 -d" ")
do
if
[ -n ${arg} ]
then
echo $(free.sh ${SPACEWARN}|grep ${arg}) | mailx -s "$arg low on space" root
fi
done

Attached is the Script I have been using for years.
I emails me when 80% of the space has been used.
