What are the contents of the $login_output variable?

According to the Net::SSH::Expect manpage, it should contain some form of response from the server: 

# 2) logon to the SSH server using those credentials.
        # test the login output to make sure we had success
        my $login_output = $ssh->login();
        if ($login_output !~ /Welcome/) {
            die "Login has failed. Login output was $login_output";
        }
