Script help

[tech123786]

Hello,
I am trying to write a script which basically check for size of the file systems and the if the file system is 100% full then it has to notify me by e-mail.
I am using df -Ik to get the %Used and get the information if it is >95% and send e-mail.Is there any different way to get this done?

Thanks

You don't need to script this! Use wsm (on an X11 window or CDE) and go to monitoring and create a monitored condition for this to send an email when the file system is 100%!

Good morning,

if you still need a script check this out:

df -k |tail +2 | awk '
BEGIN {
MAX = 90
}
{
filesystem_size = int ($4)
filesystem_name = $7
if ( filesystem_size > MAX) {
CMD=sprintf("echo \"Filesystem Alert!\" | mail -s \"Filesystem %s is
at %d Percent!\" root", filesystem_name , filesystem_size);
system(CMD);
}
}
'

This Script will send an email to root (or whatever you want like user@company.com), as soon as any filesystem is more than 90% full (you can change that via the MAX value as needed).

I hope this will help you.
That's how we used to monitor filesystems and filesystem growth on our machines.

Regards
Thomas

we use this :


TDIR=/home/techsup/tmp
SDIR=/home/techsup/stats
SLIST=/home/techsup/bin/hqserver.lst
HOST=`hostname -s`
#
# **** Check local filesystems ****
#
echo "=================================" >>$SDIR/dfchk.txt
echo "\t\t$HOST" >$SDIR/dfchk.txt
df|grep -Ev "Used|:|cd0"|awk '{print $4, $7}'|sed "s/%//g"|\
awk '{if ( $1 >=90 ) print $1," " $2 }'>$TDIR/dfchk.txt 2>&1
#
if [ -s $TDIR/dfchk.txt ];then
cat $TDIR/dfchk.txt >>$SDIR/dfchk.txt
else
echo " No filesystems are over 90% full" >>$SDIR/dfchk.txt
fi
#
mail -s (blah blah) < $SDIR/dfchk.txt
#

regards
Benno



...it really does get worse than this !!

All fine and dandy,

df -k |tail +2 | awk '
BEGIN {
        MAX = 90
...

But df can hang on a non-responding NFS server. So i prefer:

mount|\
egrep -v 'nfs|procfs'|\
awk 'NR>2{print $1}'|\
xargs df|\
grep -v Filesystem|\
awk '
BEGIN {
 MAX = 90
...

HTH,
