Way to know whether failover client is connecting?
Hi all,
Is there a way to know that a failover ActiveMQ client is now trying to connect to the brokers?
Thank you!

It works. Another question for XML configuration:
suppose I have the following network connectors config.
<networkConnectors>
<networkConnector name="host1 and host2" uri="static://(tcp://host1:61616,tcp://host2:61616)" />
<networkConnector name="host3" uri="static://(tcp://host3:61616)" />
</networkConnectors>
Does it mean that the broker has two network connectors, one will connect to either host1 or host2, while the other will always try to connect to host3.
So many questions, sorry for the bothering.

Network connections at the moment are one-way afaik. You would need to
create a network connection from the remote broker to the embedded
broker to be able to receive messages to the embedded broker. I think
there's a jira to make it two-way, but I can't remember the number... sorry.

Thank you Adrian,
I have tried as you suggested, it worked for Topic, but not queue.
The following is the code for embedded broker. As you see, I have connected embedded broker to the broker at 61616. When I send a topic, the client connected to 61616 can receive it, but I can not recieved the queue message sent by the client on 61616.
embeddedBroker = new BrokerService();
NetworkConnector connector = embeddedBroker.addNetworkConnector("static:(tcp://127.0.0.1:61616)");
connector.setNetworkTTL(2);
connector.setDynamicOnly(true);
embeddedBroker.start();

A FailoverListener would be interesting, but afaik, its not provided.

Try the TransportListener which gets notified when connections to a
broker start/stop/fail etc
http://activemq.apache.org/maven/activemq-core/apidocs/org/apache/activemq/ActiveMQConnection.html#addTransportListener(org.apache.activemq.transport.TransportListener)

When I kill the broker to test a failover, I believe the Consumer's logs show
it trying to failover to another broker.

When I kill the broker to test a failover, I believe the Consumer's logs show
it trying to failover to another broker.
