Disk Monitor
Code:
#!/usr/bin/perl

use strict;
use warnings;
use Filesys::DiskSpace;

# file system to monitor
my $dir = "/opt";

# warning level
my $warning_level=10;

# email setup
my $to='mail@mail.com';
my $subject='Low Disk Space';

# get df
my ($fs_type, $fs_desc, $used, $avail, $fused, $favail) = df $dir;

# calculate 
my $df_free = (($avail) / ($avail+$used)) * 100.0;

# compare 
if ($df_free < $warning_level) {
my $out = sprintf("WARNING Low Disk Space on $dir : %0.2f%%  ()\n",$df_free);

# send email using UNIX/Linux sendmail
open(MAIL, "|/usr/sbin/sendmail -t");

## Mail Header
print MAIL "To: $to\n";
print MAIL "Subject: $subject\n";

## Mail Body
print MAIL $out;

close(MAIL);

I commented out "Filesys::DiskSpace"

 "Filesys::DiskSpace"
any other alternative?

I do not have access to download "Filesys::DiskSpace".

I commented out this but getting following error now;


Code:
Can't call method "df" without a package or object reference at  ./test2.sh line 18.
