Could someone help me to automate disk space alert at 70 file system and send an email or text msg on solaris server? I tried this perl script but it has failed. If you have another versions please let me know. Thank you so much.

Script I tried:

#!/usr/bin/perl -w
# Script to check free diskspace and email notifications. Change the email and alert levels and you should be good to go.
# created by lb
use strict;

# Alert levels Warning and Critical - Below what percent level of free disk space do you want an alert?
my $alert1 = 40; #Warning level free space below 30%
my $alert2 = 20; #Critical level free space below 10%

# Put the email address to notify here
my $email = 'abc@abcn.com';

my ($size,$used,$avail,$use,$mounted);
my $message;
my @list;
my $sysname = `/bin/uname -n`;
chomp $sysname;
my @df = `/bin/df`;
my $df;
foreach $df (@df) {
if ($df =~ /\/\n/) {
@list = split(/\s+/, $df);
}
else {next;}
}

# Check the usage
my $diskfree = (($list[3]) / ($list[2]+$list[3])) * 100.00;

# Round the number off to 2 decimals
$diskfree = sprintf("%.2f", $diskfree);

# See if free disk space is below any of our levels
if ( ($diskfree < $alert1) && ($diskfree > $alert2) ) {
$message = "Warning Diskspace threshold reached...free space below $alert1% at $diskfree%\n";
&mailer;
}

elsif ( ($diskfree < $alert1) && ($diskfree < $alert2) ) {
$message = "Critical Diskspace threshold reached...free space below $alert2% at $diskfree%\n";
&mailer;
}

else {
$message = "Free diskspace is good at $diskfree%\n";
}

#Output to terminal (comment out if you wish)
print $message;
print "~" x 75, "\n@df","~" x 75,"\n","From system: $sysname\n";

#Subroutine for Mail, notifies on warning and critical levels.
sub mailer {
open(MAIL, "|/usr/sbin/sendmail -t") or die "Cannot open sendmail!: $!";
print MAIL "To: $email\n";
print MAIL "From: $sysname\n";
print MAIL "Subject: $message\n\n";
print MAIL "$message";
print MAIL "~" x 75, "\n@df","~" x 75,"\n","From system: $sysname";
close(MAIL);
}



Error I got was:

Use of uninitialized value in addition (+) at ./g.pl line 28.
Use of uninitialized value in addition (+) at ./g.pl line 28.
Use of uninitialized value in division (/) at ./g.pl line 28.
Illegal division by zero at ./g.pl line 28.

#### I also tried this code but got error as well on solaris...Please let me know any ideas...thanks much...

#!/bin/ksh
TEMPDIR=$HOME
FILE=mail.log
sendemail=-1
HOSTNAME="IP of the SERVER" ###ur unix server name
space=`df -bhk /users/directory |awk '{print$5}'` ## dir were u want to monitor
echo "$space is the file size percent"
#capacity=${space%?}
#capacity=$space|/usr/xpg4/bin/awk -F"[%]" '{ print $1}'
capacity=`df -bhk /users/directory| grep directory |awk '{print $5}'|sed 's/\%//'`

echo "capacity in $HOSTNAME is $capacity " >> $TEMPDIR/$FILE
if [ $capacity -gt 50 ]; then
echo "alert space in $HOSTNAME getting full "
echo > $TEMPDIR/$FILE
echo "*************************************************" >> $TEMPDIR/$FILE
echo "Problem with disk space on $HOSTNAME" >> $TEMPDIR/$FILE
/usr/bin/mailx -s "ALERT: Problem with file space on $HOSTNAME " "abc@abcd.com" < $TEMPDIR/$FILE
else
echo "enough space available"
fi

ERROR GOT:

df: (/users/directory) not a block device, directory or mounted resource

enough space available

I will post one once I find a smooth-running one and debugged.

I have a KSH that runs well but don't want to deal with KSH anymore.

If you have one, why are you asking others to write one for you, in your other thread? And did you not notice that THIS thread has been closed for TEN YEARS now?

And if by some chance the OP comes back, the error in their Perl script is easily fixed, since it has to do with df on Solaris vs Linux, and the entire error is on line 28 as they stated.

df and an old derived shell script called dfspace (used to be standard on sco and perhaps solaris) will do it.
