Re: Client to broker connection status using C++ API

[trivedi_ravi13 <tr...@yahoo.co.in>]

Hi Gordan,

   I am using following code to get the list of connections. However, I
found it gives me only first 100 connections. When I use "qpid-stat" it
shows me all the connections even beyond 100. What's wrong with this code?

int main(int argc, char** argv)
{

    Connection c("127.0.0.1:5672");

    try {
        c.open();
        Session session = c.createSession();
        Address
responses("qmf.default.topic/direct.amqpagent;{node:{type:topic},
link:{x-declare:{auto-delete:True,exclusive:True}}}");
        Receiver r = session.createReceiver(responses);
        Sender s = session.createSender("qmf.default.direct/broker");

        Message request;
        request.setReplyTo(responses);
        request.setSubject("broker");
        request.setContentType("amqp/map");
        request.setProperty("x-amqp-0-10.app-id", "qmf2");
        request.setProperty("qmf.opcode", "_query_request");
        request.setProperty("method", "request");
        Variant::Map oid;
        Variant::Map content;
        oid["_class_name"] = "connection";
        content["_what"] = "OBJECT";
        content["_schema_id"] = oid;

        encode(content, request);
        s.send(request);
        Message response = r.fetch();
        Variant::List contentIn;
        decode(response, contentIn);

        for(Variant::List::iterator it = contentIn.begin(); it !=
contentIn.end(); it++) {
            Variant::Map details = it->asMap()["_values"].asMap();
            std::cout << details << std::endl;
        }

        session.acknowledge();

    } catch(const std::exception& error) {
        std::cout << "ERROR: " << error.what() << std::endl;
    }

    c.close();
    return 0;
}

Yes it's indeed fragmented. One message contains 100 records. It worked after
handling "partial". Thank you.

If there is a lot of data, it may be sent back in multiple response 
messages (though 100 seems rather low to be triggering that on the 
normal frame size). Check whether the response has the 'partial' 
property set, and if so keep fetching another response until it does not.

You can also compare the protocol traces for qpid-stat and your code.
