How to verify and send a alarm with file system is 90% ?

[Ricardo Bassoi]

I want to check using df -k if my FS /var is with 90%. If this is true send an alarm via email.

$ df -k
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/cciss/c0d0p7 379303 119969 239751 34% /
/dev/cciss/c0d0p1 51342 7591 41100 16% /boot
/dev/cciss/c0d0p6 4553920 2532480 1790108 59% /home
/dev/cciss/c0d0p5 1007928 509444 447284 54% /opt
none 1029788 0 1029788 0% /dev/shm
/dev/cciss/c0d0p2 9224520 2224844 6531088 26% /usr

Hi,

One way to do it is with a shell script:

PCT=$(df -k /opt | tail -1 | awk '{print $1}')
if ((PCT>90)); then
echo "/opt is over 90% full" | mailx -s "/opt over 90% full" ricardo
fi


..or something like that.

Hi,

Try this:

VALUE=`df -k|grep /var|awk '{ print $5 }'|awk -F"%" '{ print $1 }'`
if [ $VALUE -gt 89 ]
then
echo "Subject: /var at $VALUE%"|sendmail user@domain
fi

This should be a very good starting point for you. Check_disk_space.sh should be cron'ed to run every 20 minutes or so. It uses a check_disk_space.cf file in the current directory to allow you to set not only the maximum threshold for critical warnings but also limits for each file system.

If you cron the script, you will probably want to set an absolute path for the .cf file rather than using the current directory.

[A. Clay Stephenson]

Here's a sample .cf file; edit it to fit your needs.

[MANOJ SRIVASTAVA]

Do the following



bdf | awk '{if ($5 > "90") print $NF,$5 }' > /tmp/test


This will create a file test in /tmp with the files sytems and the values of the usage. You can be creative in using this file as a form of mail , message etc . Run this as a part of script .
