Ths Script can be  use for to monitor filesystem free space. Threshold is amount of free MB for the filesystem

File system check script

#Script used to monitor filesystem free space
#Threshold is amount of free MB for the filesystem
THRESHOLD=$1
FILESYSTEM=$2
LOGFILE=/tmp/space_avail_$FILESYSTEM.log
HOSTNAME=`hostname`
AVAILABLE=`df -m /$FILESYSTEM | grep $FILESYSTEM | awk ‘{print
$3}’`
if [ $AVAILABLE -gt $THRESHOLD ]
then
exit 0
else
echo “$HOSTNAME – $FILESYSTEM threshold $THRESHOLD exceeded’ >
$LOGFILE
exit 1
