diskfree script doesn't seem to work.

[GrandMasterLee]

I type 'perl diskfree.pl /' and nothing gets returned to the command line.
Anyone else get that to work? TIA.

I'm using LVM on some of my volumes....but I would expect that that wouldn't cause the problem. / and /usr are not LVM, and they don't return anything either.

The problem you are having is due to the fact that 'diskfree.pl' expects a device file as input:

Code: Select all

perl diskfree.pl /dev/hda1

Should output something like:

Code: Select all

4049868:30%

Hrmmm...I tried that too...just after posting and looking at the code again..but nothing.

Code: Select all

My HDA5:
/dev/hda5              2091648    258968   1832680  13% /

Execute script:
$perl diskfree.pl /dev/hda5
$

That's it, nothing else. really odd.

Here is the code of diskfree.pl that I've got on my system from 0.6.8:

Code: Select all

#!/usr/bin/perl

$ret = `df --block-size=1024 $ARGV[0] | grep -v Filesystem`;
$ret =~ s/($ARGV[0])(.* )(.*[0-9])(.* )(.*[0-9])(.* )(.*[0-9])(.* )(.*[0-9]%)(.*
)//;

print "$7:$9";

TIA.

Ok..found something odd...
I think my term is overwriting the results...I tried it with a few other scripts, like loadavg, and memfree..no output.


I added \n to the last print, and the results show up on my command line.

That's odd, but WTF. It works

Excellent! Glad it seems to work. Make sure the scripts still work from within cacti after adding the newlines though. My first reaction tells me that they should.
