Need suggestions on formatting of BDF to get Percentage use

I have created a script in the past that would alert me when a certain filesystem reached an established threashold (s). Unfortunately, I need help with modifications because the way bdf presents results in the new environment where I work is sometimes 1 line per filesystem and sometimes 2 lines.

Attached you will find an output example for a bdf:

In my next thread I'll attach the script I used (a little modified and at this moment incomplete) in the past. However, it worked fine before because the filesystem names and rest of the bdf information only used 1 line per. In this case it is different, and when I get to the end of the script, sometimes the 2nd field ends up being the kbytes, while in other cases it may be the "kbytes used".

Please provide suggestions so that the script may work based on parameter provided. There are other things I must play with, such as the value for percentage, which a this moment is taking with the % sign and would not qualify the statement provided, but I can work with that once I have some help with the other problem presented. Any help would be appreciated!

Attached is the incomplete (and non-functioning) script.

Re: Need suggestions on formatting of BDF to get Percentage use

Hi,

I don't use 'bdf'. I use 'df' FOr ex.,

df -k /stand
/stand (/dev/vg00/lvol1 ) : 269241 total allocated Kb
197458 free allocated Kb
71783 used allocated Kb
26 % allocation used

df -k /stand |awk '/allocation used/ {print $1}'

26

This way I don't run into 'number of lines' issue.

Re: Need suggestions on formatting of BDF to get Percentage use

Go to the following site:

ftp://contrib:9unsupp8@hprc.external.hp.com/

Then go to the sysadmin directory and then the cronscripts directory.

(A direct path: ftp://contrib:9unsupp8@hprc.external.hp.com/sysadmin/cronscripts

In that directory is a script called 'diskspace.sh' that will monitor your space and take into consideration the splitting of lines in the bdf output.

Sri:

Do you have a script incorporated that checks all of the filesystems and cheks the space used by means of df -k? Thanks!

Re: Need suggestions on formatting of BDF to get Percentage use

Might be able to use my mbdf script to get better formated output.

Re: Need suggestions on formatting of BDF to get Percentage use

Hi,

A little script that I just
wrote. It cheks to see if the percent used is greater than or equal to 80% and sends a mail to yourid@yourdomain.com. Change the first two lines to your needs.

-Sri

#!/usr/bin/ksh

LIMIT=80
EMAIL=yourid@yourdomain.com

cleanup()
{
rm -f /tmp/fsreport$$
}

trap cleanup 0 1 2

for FS in $(df -l|awk '{print $1}')
do
AVAIL=$(df -k $FS|awk '/allocation used/ {print $1}')
if [ $AVAIL -ge $LIMIT ]
then
bdf $FS |sed '1d' >> /tmp/fsreport$$
fi
done

mailx -s "Disk space report on $(hostname)" $EMAIL < /tmp/fsreport$$

Re: Need suggestions on formatting of BDF to get Percentage use

Wow... Everyone, this is great and excellent contributions. I will assign points shortly. One more detail, I am not a sys admin of this system, only a second level support engineer, so in those cases where root access is required for actions I will be unable to use the script (but I will keep them for future reference). I need something simple which will allow me to get the result without much more access than the limited access I have (use of bdf or df -k provides me with results I can use).

Thanks everyone for your prompt assistance, look for your points shortly!

Re: Need suggestions on formatting of BDF to get Percentage use


I think I will end up using Sanjay's script, it provides an output that I really like. Of course, everyone's help is appreciated.

Sri, as simple as your script is, it does the job perfectly.

Steven, something happened to the file you attached, it's either incomplete or the file was sent binary and it messed up the format. Sorry, but I was unable to read/use, I'll reassign points if you decide to re-attached in ascii.

Patrick, I will keep yours for when I go back to doing sys admin stuff.

Thanks everyone for providing a very quick solution.

Re: Need suggestions on formatting of BDF to get Percentage use

Hi,

My script doesn't need to be run as root. 'df' and 'bdf' commands can be executed as an ordinary user.
