How to get monitor information ?

I'm not sure how you are coding things, but for addtitional out parameters in SOAP::Lite you need to use paramsout to get an array of additional parameters.

$soapResponse = $soap->get_use_http(...);
$bUseHttp = $soapResponse->result;
@params = @{$soapResponse->paramsout};
$send_string = $params[0];
$get_string = $params[1];
$recv_string = $params[2];
$user_name = $params[3];
$password = $params[4];

Let me know how this works for you. If not, post some code of what you are doing so I can see if there is anything obvious. -Joe
