Mount point space

jayraj005 · 05-18-2009, 06:28 AM

Hi All,

I would like to write a shell scripts which sends the mail when the mount point filled the 90 percent space.

cat test.sh
#!/bin/ksh
timestamp=`date +"%Y_%m_%d"`
LOG=/stage/scripts/space_usage.log
FS=' ' # field separator
#df -k|awk '{print $4,$5,$6}' > /tmp/test.txt
#df -k|awk '{print $4,$5,$6}'|sed 's/%/ /g' > /tmp/test.txt
#df -kh |awk '{print $4," ",$5}'|sed -e 's/%//g' -e '1,1d' > /tmp/test.txt
df -kh|grep -v cciss|grep -v intfdata|grep -v Available|grep -v none|grep -v stage|awk '{print $4,$5}'|sed -e 's/%//g' -e '1,1d' > /tmp/test.txt
cat /tmp/test.txt | while read string; do
percent_used=`echo "$string" |awk -F' ' '{print $1}'`
mount_point=`echo "$string" |awk -F' ' '{print $2}'`
echo "percent used "
echo $percent_used
echo "mount point "
echo $mount_point
if [ $percent_used > 90 ]
then
printf "\n $percent_used is greater than 90 \n"
else
printf "\n $percent_used is smaller than 90 \n"
fi
done
rm /tmp/test.txt

The above if condition is not working fine. It seems due to spaces. Can any one help on this.

Seems rather long winded:

Code:

!#/bin/sh
USED=$(df /home| tail -n 1 | awk '{print $4}' | cut -d '%' -f 1)

if [ ${USED} > 90 ]
then
     echo "${USED} is greater than 90"
else
     echo "${USED} is less than 90"
fi

Even shorter

Code:

if [ $(/bin/df /home|tail -n 1|awk '{print $5}'|cut -d% -f1) -lt "90" ] ; then echo "All is well"; else echo "Attention! Disk space" ; fi

I need the script which can mail me if mount point filled more than 90 % . In our case we are having more than one mount point.

You're using the wrong operator: http://www.tldp.org/LDP/abs/html/refcards.html#AEN21463

Blinker_Fluid · 05-22-2009, 09:37 AM

maybe this will help maybe it won't

Code:

#!/bin/bash
rm ~/latest_problem_with_disk_space
for i in `df -h | grep -v capaci | awk '{print $5}' | cut -d% -f1` ; do if [ $i -lt 90 ]; then echo "good" ; else echo "we have a problem on `df -h | grep $i `" >> ~/latest_problem_with_disk_space ; fi ; done
if [ -e ~/latest_problem_with_disk_space ] ; then mailx -s "FileSystem Full alert" your_email@yourcompany.com < ~/latest_problem_with_disk_space ; fi

jayraj005 · 05-25-2009, 12:45 AM

Thanks Fluid for the script. I will try your suggestion.

jayraj005 · 05-26-2009, 04:49 AM

That won't helped. The message is coming for each mount point.

From the above output. I need the script which atleast alert when the mount point filled 90%

Blinker_Fluid · 05-26-2009, 09:20 AM

Maybe it's what I'm evaluating the wrong item

what does this return?

df -h | grep -v capaci | awk '{print $5}' | cut -d% -f1

Should be the disk percentages minus the % sign (working on a Solaris server so it may display different).

AnanthaP · 05-26-2009, 10:32 PM

At present, I am on a Solaris system where a fairly longwinded awk as below does it. It should work for all distros.
Essentilly, `DF` TAKES ALL BLOCKS AS 512 bytes. This is useful to report in megabytes (1048576 bytes). The awk computes the percentage and based on your threshold, the results are filtered and piped to your mail programme.

In Solaris, this comes as /usr/bin/dfspace and is a shell script.

df -t | awk '{ .. }' | sendmail <mymailid>

End

jayraj005 · 05-26-2009, 11:31 PM

Output for following command
$ df -h | grep -v capaci | awk '{print $5}' | cut -d% -f1

Blinker_Fluid · 05-27-2009, 10:51 AM

It's returning the mountpoint also which is confusing the script. It should just return the percent minus the percent sign. I believe you were closer when you had

df -kh|grep -v cciss|grep -v intfdata|grep -v Available|grep -v none|grep -v stage|awk '{print $4,$5}'|sed -e 's/%//g' -e '1,2d'

except in the script just return the $4 value that showed the % filled.

I took what you had earlier and modified to what I believe would work.

Code:

#!/bin/bash
rm ~/latest_problem_with_disk_space
for i in `df -kh|grep -v cciss|grep -v intfdata|grep -v Available|grep -v none|grep -v stage|awk '{print $4}'|sed -e 's/%//g' -e '1,2d'` ; do if [ $i -lt 90 ]; then echo "good" ; else echo "we have a problem on `df -h | grep $i `" >> ~/latest_problem_with_disk_space ; fi ; done
if [ -e ~/latest_problem_with_disk_space ] ; then mailx -s "FileSystem Full alert" your_email@yourcompany.com < ~/latest_problem_with_disk_space ; fi
