Script to notify by mailx if disk is almost full 3

[IThead]

Hi,
Does anyone has any script that can check the disk usage by percentage? if any disk that is >90% (using df -k) will email an alert.

Thanks

strange error message.......

Are you sure the 3 arguments you pass to 'CHK_FILE_SPC' function are quoted with single quotes with spaces between the arguments?

What OS are you on?

On hp-ux try using bdf instead of df.

Hi,

The arguments are correct.
CHK_FILE_SPC '/' '10' '%'

The O/S is HP-UX 11.00

Thanks

 

[TheDash]

Hi, Any clues? Thanks

 

[Chacalinc]

what is the line 14? could you post it?

 

[TheDash]

Thanks for the response. The execution pauses for about 6 seconds before giveing this error

Line 14 is

export PATH=/usr/bin:/usr/sbin:/bin:/sbin:/usr/local/bin:

And what happens if you add set -x in the beginning of the CHK_FILE_SPC function ?

Hope This Help, PH.

I think the problem is here:

LOW_WATER_MARK = $AMOUNT * 1024

AMOUNT is get from:

export AMOUNT=`$DF $FILESYS | tail -1 | awk -v PERCENT=$2 '{print $2*PERCENT/100/1024}'`

and it is resulting in a float number, not integer. Try the commands by hands.

On hp-ux try using bdf instead of df.

 

[TheDash]

Sorry abt the delay. Ygor, gotta do this with df cmd only .. I will use bdf later....

Chacalinc, I verified.. it gives a float result. Now, I think LOW_WATER_MARK can't be defined as "integer". I tried "float" but it gives an error.

PHV, set -x at the beginning of the CHK_FILE_SPC function gives

+ date +%m%d
+ export DATE=0331
+ export TMP=/tmp/.chkfilspc.0331
+ export PATH=/usr/bin:/usr/sbin:/bin:/sbin:/usr/local/bin:
+ hostname
+ export HOSTNAME=fddsms
+ export PROGRAM=temp.sh
+ export PAGE=/usr/local/bin/sendpage -n
+ export DF=df -k
+ set -x
+ CHK_FILE_SPC / 10 %
+ export FILESYS=/
+ [ % = % ]
+ df -k /
+ tail -1
+ awk -v PERCENT=10 {print $2*PERCENT/100/1024}
+ export AMOUNT=0
+ typeset -i FREE_SPACE LOW_WATER_MARK
+ + df -k /
+ tail -1
+ awk {print $3}
temp.sh[15]: allocation: The specified number is not valid for this command.

Line 15 is: export HOSTNAME=`hostname`

The problem is the format of df -k on hp-ux. Here's a demonstration..

$ export DF="df -k"
$ export FILESYS=/
$ FREE_SPACE=`$DF $FILESYS | tail -1 | awk '{print $3}'`
$ echo $FREE_SPACE
allocation

What you need to get the free space is the fourth field from bdf (or df -Pk)...

$ export DF="[highlight]bdf[/highlight]"
$ FREE_SPACE=`$DF $FILESYS | tail -1 | awk '{print [highlight]$4[/highlight]}'`
$ echo $FREE_SPACE
