reporting disk usage with df -vk command 1

[Marcel1958]

Hello experts,

I have to report (by email) on a daily basis(using the df -vk command):

1 the total amount of disk usage
2 signal if the usage of a file system is > 80%

Who can help me with a usefull script?

Regards

Marcel

Is this sort of thing any good?

#!/bin/ksh
clear
echo " Checking File Systems"
echo
echo "Mount Total Used Free Used% Test"
echo xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
df -k |grep /| awk '{$2 = $2 /1000; $3 = $3 /1000 ; {if ($5>80 || $5=="100%&quot $
9 = "warning"}; $4 = $4 /1000; printf "%-15s " "%8.1f Mb " "%
8.1f Mb" "%8.1f Mb\t%5s%10s\n" ,$6, $2, $3,$4,$5,$9}'|sort
echo xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
echo
echo "Check file systems with warning"
echo

Should have explained a bit.

This script uses df -k. If you want to use df -vk (which gives a different output column structure) then you'll need to change the awk script to manage the columns correctly.

If you want to mail the output, you can do something like <scriptname> | mail <username>

Thanks Greg for your response.

As you can see is the result of the command not correct. I have included the result of the df -k command. Can you help me further and also explain the command.

I need also the totals of the free and used blocks.

Hi,

With HP, the df -vk give output like :

hp>df -kv .
[tt]/tmp (/dev/vg00/lvol6 ) : 62414 total allocated Kb
47592 free allocated Kb
14822 used allocated Kb
23 % allocation used
[/tt]

You can use the following awk script :

dfvk.awk

function PrintInfos( sts) {
if (FileSystem != &quot;&quot {
sts = &quot;&quot;;
if (PUsed > 80) sts = &quot;WARNING&quot; ;
printf OutFmt, FileSystem, Total, Free, Used, PUsed, sts;
}
}
BEGIN {
OutFmt = &quot;%-24s %8s %8s %8s %3s %% %s\n&quot; ;
printf OutFmt,&quot;FileSystem&quot;,&quot;Total&quot;,&quot;Free&quot;,&quot;Used&quot;, &quot;&quot;, &quot;&quot; ;
}
{
InfoField = NF-3;
}
/ total allocated/ {
PrintInfos() ;
FileSystem = $1 ;
Total = $InfoField;
}
/ free allocated/ {
Free = $InfoField;
}
/ used allocated/ {
Used = $InfoField;
}
/ % allocation used/ {
PUsed = $InfoField;
}
END {
PrintInfos() ;
}

Example:

hp0> df -vk | awk -f dfvk.awk
[tt]FileSystem Total Free Used %
/home 19354 17782 1572 8 %
/opt 502263 148106 354157 70 %
/tmp 62414 47592 14822 23 %
/usr 812434 102422 710012 87 % WARNING
/var 806609 190461 616148 76 %
/stand 75359 47458 27901 37 %
/ 137423 89168 48255 35 %

As Jean Pierre said, these scripts are somewhat platform dependent. The one I posted was for Solaris. What platform are you using?

Greg.

Thanks Jean Pierre and Greg for your response.

We are running AIX 4.3.3

Greg,

I tried running your script and got the following messages:
Checking File Systems

Mount Total Used Free Used% Test

diskmon: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xx: not found
awk: syntax error near line 2
awk: illegal statement near line 2
awk: newline in string near line 3
awk: syntax error near line 4
awk: illegal statement near line 4

diskmon: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xx: not found

Check file systems with warning

Do I kick off the script (called diskmon) as the name or with awk in command line such as:[tt]
#diskmon[/tt]

#df -k | awk -f diskmon[/tt]
Both didnt work for me.

Please advise what I am doing wrong?
