Shell script for checking filesystems

[Matjaz Obstetar]

Hi,

I would like to check available space of each filesystem on my box with the shell script. This script I will run from the cron. When the available space decrease under the limit I would like to get the message in my mail box.
Could you help me and tell me where can I get a script with my requirements.

Thanks,

Matjaz

Hi,
This script will run on Virtual Vault, so 3-rd party software is irrelevant. The system is without Perl too.

try this

if [[ $(print $MOUNT | awk ' { print substr($1,1,1) } ') != '#' && $(print $
MOUNT | awk ' { print substr($1,1,1) } ') != '' ]] then
if bdf | egrep -v egrep | egrep $MOUNT 1>/dev/null 2>&1
then PERUSED=$(bdf $MOUNT | egrep -v [Uu]sed | awk {'print $5'})
PERUSED=${PERUSED%'%'}
if [[ $PERUSED -gt $PERCENTFLAG ]] then
print "${0##*/}: $MOUNT file system is $PERUSED% full"
echo "${0##*/}": $HOSTNAME $MOUNT file system is $PERUSED% full | mail
x -s "file system full" root
else
print "$MOUNT $PERCENTFLAG% OK..."
fi
else
print "file system $MOUNT does not exist"
fi

---------
config file like this

/home 80
/u101 90
/u102 90
/u103 90
/u104 90

---------
#fscheck config_file
it will checking with bdf , if exceed as specify in config file , it will mail to root.

---------
I cut from a part of a script , may be you need to modify

In ./scfs.dat, I put my static file systems, one fspath in each line, I don't want check them.

Try diskspace.ksh from:

ftp://contrib:9unsupp8@hprc.external.hp.com/sysadmin/cronjobs/

You can customize the script to set different limits for each filesystem.

I just posted this today in another message thread. See the message "What is the best way to configure performance alert", there's an attachment there that is a script file that I use.
