Filesystem monitoring script

[Narendra Uttekar]

Hi,
I am running this script in cron job...but the problem is that even if the threshold doesn't exceed i am getting an blank e-mail for this script and if the threshold exceed i am getting the mail for the alerts which is fine. But i don't want any blank mail if threshold doesn't exceed as this unnecessary full my inbox.
bdf /oracle/TCP/saparch |awk 'NF==1{f=$0;getline;$0=f$0}{if($5+0>65)print}' > mailx -s"FileSystem on HOSTNAME" narendra@xxxxx.com

Thanks,
Narendra

You are getting this mail because everytime cron is running its sending output of the command to you mail as u asked it to do.
When ur filesystem is not >65 output of bdf /oracle/TCP/saparch |awk 'NF==1{f=$0;getline;$0=f$0}{if($5+0>65)print}' is balnk and its going to ut mailbox.

If you do not want blank mails you have to guide it using if else statment
if output >65
mail
else
nothing ;)

Let us know if you need exact statments.

Hi,

Please download this file (bdfmesg) from below link you will find this is a great tool written by Mr.Bill Hassell.

http://forums13.itrc.hp.com/service/forums/questionanswer.do?threadId=1326767

Just give

#bdfmesg -P 80 ##to find all file system which is using 80 or more then 80

Like so many output you can take from bdfmesg

Many Thanks to Mr.Bill Hassell to create a nice and useful tool.

There are a bunch of scripts to handle thresholds in this thread:

[Kapil Jha]

you may have to put this line in some scripts say..abc.sh
#!/usr/bin/sh
abc=`bdf /oracle/TCP/saparch |awk 'NF==1{f=$0;getline;$0=f$0}{if($5+0>65)print}'`

if [ abc != null ] ; then
abc > mailx -s"FileSystem on HOSTNAME" narendra@xxxxx.com
else
echo "free" >/dev/null
fi

Hi,
Kapil i tried your script but while running gives an error [./disk2.sh[4]: abc: not found.]
I don't know much of the scripting, please let me know what to correct.

Thanks,

Hi,
Kapil for monitoring the file system i am using this 2 scripts. But the problem with this script is that it doesn't sent me the alert for /oracle/TCP/saparch , /oracle/TCP/102_64 and /usr/sap/TCP. For all other file systems i am getting alerts. I don't know why it is not working as expected. That's why i thought i will run other script to monitor this file system.
Please find the attached scipts, please let me know if any correction required so that i can modify the same, so that i can start receiving the alerts for this file system as well.

The second script is attached now...

[Viktor Balogh]

hi narenda,

this line has bad syntax:
if (("${PCT}>${MAX_THRESH}"))

the correct way to check if the percent is larger than allowed is:

if [ "${PCT[$i]}" -gt "${MAX_THRESH[$i]}" ]
then
.... do some useful things
fi


the '[ ]' symbols after the if statement are abbreviations for the test command, try 'man test' for more info...
( -gt is for "greater than" )


mark that you should use the arrays this way:

${VARIABLE[$index]}

[Viktor Balogh]

here is a possible solution in the attachment, just modify the ${CONF_FILE} variable to your needs!

[Viktor Balogh]

and this is the conf file with the thresholds...

[Narendra Uttekar]

Hi,
Viktor thanks for the info...i modified the scripts as you suggested, but while executing i am getting an error as below,
./disk.sh[17]: /tmp/sapwork: syntax error
./disk.sh[17]: /opt/sapbc47: syntax error
./disk.sh[17]: /sapmnt/TCP: syntax error
./disk.sh[17]: /usr/sap/TCP: syntax error

But /var /opt /home /tmp are excuting properly without an error but it gives an error /opt/sapbc47
Please advise what syntax correction needs to do...Thanks

[Dennis Handly]

>./disk.sh[17]: /tmp/sapwork: syntax error

The config file should look like this:
FS[0]=/ ; TRESH[0]=40
...
