Hello aditya1977,

In the spirit of TMTOWTDI, here’s a concise implementation of LanX’s hash slice solution:

#! perl
use strict;
use warnings;
use Data::Dump;

my %nodemetrics;
my @nodelist   =  qw(server1 server2);
my @attributes =  qw(memory cpu disk network);
my $string     = '1024|2200|30|100';
my @data       =  split /\|/, $string;

@{  $nodemetrics{$_     } }{@attributes} = (0) x @attributes for @node
+list;
dd \%nodemetrics;
@{  $nodemetrics{server1} }{@attributes} = @data;
dd \%nodemetrics;

Output:

22:03 >perl 1027_SoPW.pl
{
  server1 => { cpu => 0, disk => 0, memory => 0, network => 0 },
  server2 => { cpu => 0, disk => 0, memory => 0, network => 0 },
}
{
  server1 => { cpu => 2200, disk => 30, memory => 1024, network => 100
+ },
  server2 => { cpu => 0, disk => 0, memory => 0, network => 0 },
}
