Discover Device (Perl code sample)

[CodeCentral_194]

Problem this snippet solves:

This Perl client code sample uses Enterprise Manager's device inventory to discover a list of devices managed by the referenced Enterprise Manager.

Code :

#!/usr/bin/perl

use strict;
use SOAP::Lite;

use constant MIN_ARGS => 3;
use constant NUM_DEVICE_ARGS => 3;
use constant USAGE => "Management_EM_discover_devices    [  ] ...";

#
# Parse command line arguments.
#

my $num_args = $#ARGV + 1;

if (($num_args < MIN_ARGS) || ((($num_args - MIN_ARGS) % NUM_DEVICE_ARGS) != 0)) {
    print "Usage: ", USAGE, "\n";
    exit();
}

my $em_host = $ARGV[0];
my $em_username = $ARGV[1];
my $em_password = $ARGV[2];

my $num_devices = ($num_args - MIN_ARGS) / NUM_DEVICE_ARGS;

my @device_address_list;
my @device_username_list;
my @device_password_list;

for (my $i = 0; $i < $num_devices; $i++) {
    my $offset = MIN_ARGS + ($i * NUM_DEVICE_ARGS);

    push (@device_address_list, $ARGV[$offset]);
    push (@device_username_list, $ARGV[$offset + 1]);
    push (@device_password_list, $ARGV[$offset + 2]);
}

#
# Create SOAP proxy.
#

my $soap = SOAP::Lite
    -> uri('urn:iControl:Management/EM')
-> proxy("https://$em_username:$em_password\@$em_host/iControl/iControlPortal.cgi");

#
# Start the device discovery.
#

my $soap_response = $soap->discover_devices
    (
        SOAP::Data->name(addresses => [@device_address_list]),
        SOAP::Data->name(usernames => [@device_username_list]),
        SOAP::Data->name(passwords => [@device_password_list])
    );

if ( $soap_response->fault )
{
    print $soap_response->faultcode, " ", $soap_response->faultstring, "\n";
    exit();
}

my $task_id = $soap_response->result;

print "Discovery task started with task ID: $task_id\n";
