Perl array / json

Hi All

I have used the below code to print the dumper of a json

Code:

#!/usr/bin/perl

use LWP::Simple;                
use JSON qw( decode_json );     
use Data::Dumper;               
use strict;                     
use warnings;

my (%list);                 

my $trendsurl = "http://sensu:4567/events";

my $json = get( $trendsurl );
die "Could not get $trendsurl!" unless defined $json;

my $decoded_json = decode_json( $json );




print Dumper $decoded_json;

which gives me the following

Code:

$VAR1 = [                                                                                                                                                                                           
          {                                                                                                                                                                                         
            'client' => 'es1.',                                                                                                                                                            
            'flapping' => bless( do{\(my $o = 0)}, 'JSON::XS::Boolean' ),
            'check' => 'disk_usage',
            'occurrences' => 2160,
            'issued' => 1371466494,
            'status' => 1,
            'handlers' => [
                            'default'
                          ],
            'output' => 'com.dneg.es1.df.boot.df_complex.free OK
WARNING: com.dneg.es1.df.opt-elasticsearch.df_complex.free will run out of space in 10 days at current rate
com.dneg.es1.df.root.df_complex.free OK
'
          },
          {
            'client' => 'graphite1.',
            'flapping' => $VAR1->[0]{'flapping'},
            'check' => 'disk_usage',
            'occurrences' => 7028,
            'issued' => 1371466494,
            'status' => 1,
            'handlers' => [
                            'default'
                          ],
            'output' => 'com.dneg.graphite1.df.boot.df_complex.free OK
com.dneg.graphite1.df.root.df_complex.free OK
WARNING: com.dneg.graphite1.df.user_data.df_complex.free will run out of space in 12 days at current rate
'
          },

I am now stuck in how to use that data, i want to extract the client and the Warning

i.e

client' => 'graphite1.
WARNING: fee will run out of space in 12 days at current rate

any pointers would be great

Thanks

TM::Materialized::JTM(3pm)				User Contributed Perl Documentation				TM::Materialized::JTM(3pm)

NAME

       TM::Materialized::JTM - Topic Maps, trait for JSON Topic Map instances.

SYNOPSIS

	 use TM::Materialized::JTM;
	 my $tm=TM::Materialized::JTM(file=>"somefile.jtm");
	 $tm->sync_in;
	 ...
	 # map was modified, now save the changes
	 $tm->sync_out;

DESCRIPTION

       This package provides map parsing and creating functionality for JTM (JSON Topic Map) instances.  The JSON Topic Map format is defined
       here: <http://www.cerny-online.com/jtm/1.0/>.

INTERFACE

   Methods
       Constructor
	   $tm = TM::Materialized::JTM->new (...);

	   The constructor expects a hash as described in TM::Materialized::Stream, with one additional key/value parameter:

	   o   format (choices: "json", "yaml")

	       This option controls whether the JTM data is treated as being in JSON format or in YAML (which is a superset of JSON). This applies
	       to both reading and writing of map data.

	       The default value is "json".

       format
	   $tm->format('json');

	   $curformat=$tm->format;

	   This method gets or sets the format parameter for future operations. Possible choices: "json", "yaml".
