Rex::Hardware - Base Class for hardware / information gathering
=head1 DESCRIPTION
This module is the base class for hardware/information gathering.
=head1 SYNOPSIS
use Rex::Hardware;
my %host_info = Rex::Hardware->get(qw/ Host /);
my %all_info = Rex::Hardware->get(qw/ All /);
=head1 CLASS METHODS
=cut
package Rex::Hardware;
use strict;
use warnings;
our $VERSION = '1.4.1'; # VERSION
use Rex::Logger;
require Rex::Args;
=head2 get(@modules)
Returns a hash with the wanted information.
task "get-info", "server1", sub {
%hw_info = Rex::Hardware->get(qw/ Host Network /);
};
Or if you want to get all information
task "get-all-info", "server1", sub {
%hw_info = Rex::Hardware->get(qw/ All /);
};
