script required to monitor disk space usage

[Jagadesh_2]

Hi All,

/dev/hd3 1048576 637700 40% 579 1% /tmp
/dev/REMlv01 7340032 2017712 73% 22145 5% /u01
/dev/REMlv02 18874368 7538816 61% 31 1% /u02
/dev/REMlv03 6291456 3622456 43% 27 1% /u03
/dev/REMlv04 12582912 5962408 53% 82 1% /u04
/dev/REMlv00 2097152 1536616 27% 3348 1% /app/remedy

I need a single script which can monitor the following filesystems. If the filesystem usage crosses 65% then it shoud through a mail alert to me. How can i go about in doing the same. I have a script to monitor a single filesystem

while true
do
u04=`df -k|grep REMlv04|awk '{print $4}' | cut -c -2`
if [ $u04 -gt 60 ]
then
echo "/u04 File System is getting full " > /home/in263054/mail
mail -s "Filesystem Warnings" test@test.com < /home/in263054/mail
fi
break
done


Thanks in advance

Hi,

With this script, you can use a standard limit or you can define a limit for each tablespace:

Script---:
EMAILS="YourEmail@domain.com"
TABSPACO=/usr/local/etc/TabSpaco
TABMSG=/tmp/msg.$$
>${TABMSG}
BDF=/tmp/bdf.$$
>${BDF}
bdf | grep -v Mounted >${BDF}
while read a b c d e f
do
spc=`echo $e|sed 's/%//'`
set `grep $f $TABSPACO` >/dev/null 2>/dev/null
SPC=$1
if [[ $SPC -eq "" ]]
then
SPC=65
fi
if [[ $spc -gt $SPC ]]
then
echo "$f => % occupied = $e" >>${TABMSG}
fi
done <${BDF}
test -s ${TABMSG}
if [[ $? -eq 0 ]]
then
elm -s "FILESYSTEM SPACE" $EMAILS <${TABMSG}
fi
rm ${BDF}
rm ${TABMSG}

-->TabSpaco - modify as required:
80 /
80 /stand
80 /var
95 /usr
80 /usr/local/samba
80 /tmp
80 /sys
99 /opt
80 /home

Hi


You already got some good answers

You can control all file system by redirecting all file system informations into a temporary file as,

#!/bin/ksh
FSFILE=/tmp/fs.log

# Remove first line
# You can also use bdf.
df -k | grep -v 'Mounted' > /tmp/fs.log

while read fs use avail per;
do
if [[ $(echo $per|cut -d% -f 1) -gt 65 ]]
then
mail -s "$fs in $(hostname) is over 65%" test@test.com
fi
done < /tmp/fs.log

# end
exit 0

It is good to put this script in cron schedular to execute per minute.

hth.

You could use the Event Monitoring Service, under Resource Management in SAM to do this.

For each filesystem, you can set the minimum amount of free space (I don't think you can give a percentage, unfortunately), and it can be configured to send you email when it crosses the limit.

See http://www.docs.hp.com/en/B7612-90015/index.html for more details.
