how to access the activemq statistics plugin in .net - activemq

Question

I am trying to access the activemq statistics information http://activemq.apache.org/statisticsplugin.html in c#
This is what i have so far. I am not able to get a reply from the consumer. I can the count increase in monitor website for the queue.
public class Statistics
{
private readonly string queueName = string.Empty;
private readonly string queueToMonitor = string.Empty;
private readonly IConnectionFactory connectionFactory;
private readonly IConnection connection;
private readonly ISession session;
private readonly IMessageProducer producer;
private readonly ActiveMQQueue queue;
public Statistics(string qName, string brokerUri, string queueToMon)
{
this.queueName = qName;
this.queueToMonitor = "ActiveMQ.Statistics.Destination." + queueToMon;
this.connectionFactory = new ConnectionFactory(brokerUri);
this.connection = connectionFactory.CreateConnection();
this.connection.Start();
this.session = connection.CreateSession();
queue = new ActiveMQQueue(qName);
producer = session.CreateProducer(queue);
}
public void GetStats()
{
try
{
var statusQueue = session.CreateTemporaryQueue();
var consumer = session.CreateConsumer(statusQueue);
ActiveMQQueue query = new ActiveMQQueue(queueToMonitor);
var msg = session.CreateMessage();
msg.NMSReplyTo = statusQueue;
producer.Send(queue, msg);
var reply = (ActiveMQMapMessage)consumer.Receive();
if (reply != null)
{
var test = reply.Content.ToString();
}
}
catch (Exception e)
{
var t = e.Message + " " + e.StackTrace;
}
}
}

You are sending the message to the wrong queue. You need to send the message to the ActiveMQ.Statistics.Destination.QueueToMonitor destination. I re-wrote your GetStats() function to show that it works. The critical change is which destination the producer sends the message to.
public void GetStats()
{
try
{
IDestination statusQueue = session.CreateTemporaryQueue();
IMessageConsumer consumer = session.CreateConsumer(statusQueue);
IDestination query = session.GetQueue(queueToMonitor);
IMessage msg = session.CreateMessage();
IMessageProducer producer = session.CreateProducer(query);
msg.NMSReplyTo = statusQueue;
producer.Send(msg);
IMapMessage reply = (IMapMessage) consumer.Receive();
if(reply != null)
{
IPrimitiveMap statsMap = reply.Body;
foreach(string statKey in statsMap.Keys)
{
Console.WriteLine("{0} = {1}", statKey, statsMap[statKey]);
}
}
}
catch(Exception e)
{
var t = e.Message + " " + e.StackTrace;
}
}
