This is one of my first perl apps and I'm having issues pushing a hash into an array.

The code sample is below, I've documented the place where the problem lies. Any help would be greatly appreciated. Thanks in advance.

#!/usr/bin/perl

my $RESULT="OK";

use strict;
use warnings;

my $STATE_OK=0;
my $STATE_WARNING=1;
my $STATE_CRITICAL=2;
my $STATE_UNKNOWN=3;

my %error_code = (
        SysBatteryFailure               => 'System Battery Failure',
        PowerRedundencyFailure          => 'Power Redundency Failure',
        FltTolPowerSupplyFailed         => 'Fault Tolerant Power Suppl
+y Failure',
);

my $SysBatteryFailure=`echo \"Battery Failure\" | grep Failure`;
my $PowerRedundencyFailure=`echo \"Power Redundency Failure\" | grep t
+rash`;
my $FltTolPowerSupplyFailed=`echo \"Power Supply Failure\" | grep tras
+h`;

my @STATUS = ($SysBatteryFailure, $PowerRedundencyFailure, $FltTolPowe
+rSupplyFailed);

my @ILO_ERRORS = ();

foreach my $element (@STATUS) {
  chomp $element;
  if ($element)
  {
    # The element variable is accurate here
    print "$element\n";
    # the following line fails.  I want to push the hash
    # into the array.  Any idea why it fails?
    push (@ILO_ERRORS, $element);
  }
}

if (@ILO_ERRORS) {
  print "SNMP CRITICAL - ", @ILO_ERRORS;
  exit $STATE_CRITICAL;
} else {
  print "SNMP OK - $STATE_OK";
  exit $STATE_OK;
}

The result of this code is:

root@yosemite SNMP# ./2

Battery Failure

Use of uninitialized value $ILO_ERRORS1 in print at ./2 line 37.

SNMP CRITICAL - HASH(0x11f1018)

root@yosemite SNMP# vi 2
