Since you only want the connection status, you probably should use the POE::Wheel::SocketFactory instead of the component (which is built on top of SocketFactory). Something like the following:( not tested, not even syntax) 
use strict;
use POE;
use POE::Wheel::SocketFactory;

my $task = [
    { name => 'www.example.com',  proto => 'tcp', port => 80 },
    { name => 'smtp.example.com', proto => 'tcp', port => 25 },
    { name => 'ns.example.com',   proto => 'udp', port => 53 },

];

for my $t( @$task ) {
    POE::Wheel::SocketFactory->new(
        RemoteAddress  => $t->{host},
        RemotePort     => $t->{port},
        SocketProtocol => $t->{proto},
        SuccessEvent      => sub {
            print "$t->{host}:$t->{proto}:$t->{port} up\n";
            $poe_kernel->yield( 'shutdown' );
        },
        FailureEvent   => sub { print "$t->{host}:$t->{proto}:$t->{por
+t} down\n" },
 
    );
}

$poe_kernel->run();
