How to know all the available topics

[Davide Anastasia <Da...@qualitycapital.com>]

Is there a way to discover all the available topics to a certain
exchange (let's say, amq.topic).

 

Thanks,

Hi Davide,
does the command:

qpid-config exchanges amq.topic -b 

fulfill your needs?

To have it implemented in a client, it is possible to invoke a QMF command to list all bindings. Something like the C++ program below (not sure how to write the query to filter bindings from just some exchange).

Kind regards,
Pavel


// begin of list_binginds.cpp
#include <qpid/messaging/Connection.h>
#include <qpid/messaging/Session.h>
#include <qpid/messaging/Sender.h>
#include <qpid/messaging/Receiver.h>
#include <qpid/messaging/Message.h>
#include <qpid/messaging/Address.h>

#include <iostream>

using namespace std;
using namespace qpid::messaging;
using namespace qpid::types;

int main(int argc, char** argv) {
  Connection c(argc>1?argv[1]:"localhost:5672");
  c.open();
  Session session = c.createSession();
  Receiver r = session.createReceiver("#qlister; {create:always, delete:always}");
  Sender s = session.createSender("qmf.default.direct/broker");

  Message m;
  m.setReplyTo(Address(r.getName()));
  m.setProperty("x-amqp-0-10.app-id", "qmf2");
  m.setProperty("qmf.opcode", "_query_request");

  Variant::Map request;
  request["_what"] = "OBJECT";
  Variant::Map schemaId;
  schemaId["_class_name"] = "binding";
  request["_schema_id"] = schemaId;

  encode(request, m);
  s.send(m);
  m = r.fetch(3 * Duration::SECOND);
  session.acknowledge(m);
  Variant::List response;
  decode(m, response);
  for(Variant::List::iterator iter = response.begin(); iter != response.end(); iter++) {
    Variant::Map map = iter->asMap();
    cout << map << endl;
    Variant::Map values = map["_values"].asMap();
    cout << values["name"] << endl << endl << endl;
  }
  r.close();
  s.close();
  session.close();
  c.close();
  return 0;
}
// end of list_binginds.cpp
