Hi,

The ERROR line in the log is a "false error" that log should actually be a INFO.
Debugging the embedded broker is not very easy since he don't have access
to ActiveMQ web console.

In fact you can consider the broker is correctly enable if you have something like this:

21 Sep 17:17:50 ERROR [cluster.impl] - Started the embedded brokerURI: BrokerService[f088d295-ab15-470a-a45e-bba8cc3fad8a]

Hi Andrea,

The GUI page indicates Embedded broker is enabled.

Logs appear to indicate broker is enabled. Getting messages like:

2016-09-21 08:02:56,277 ERROR [cluster.impl] - Started the embedded brokerURI: BrokerService[3404d32d-6cd6-4ccb-a9f8-2ee428c12977]

2016-09-21 08:02:56,277 INFO [cluster.impl] - Using brokerURI: vm://3404d32d-6cd6-4ccb-a9f8-2ee428c12977?create=false&waitForStart=5000

Although we are not sure why the Started the embedded line indicates ERROR (is this a true error; or false reprting)

As I think we can conclude embedded broker is enabled, looking at the network is our second troubleshooting step so we will investigate that angle.

Thanks for your feedback.

Kevin

Hi Kevin,

I'm just going by memory, but believe you can simply look at the configuration page for the cluster to

check if the embedded broker is enabled? It should also be logging on the logs on startup.

However, per to peer in the default configuration requires multicast to be enabled in your network, so that nodes

can find each other. Is that the case for you?

Cheers

Andrea

    Hello,

    We have set up clustering between 2 geoservers. We want to
    implement the "Peer-to-peer newtork with embedded brokers and
    shared data directory" topology.

    We are using the default cluster configuration (broker.xml;
    cluster.properties; embedded-broker.properties). However, the
    geoserver.log is reporting errors like:

    2016-09-21 08:10:43,834 WARN [network.DiscoveryNetworkConnector] -
    Could not start network bridge between:
    vm://3404d32d-6cd6-4ccb-a9f8-2ee428c12977?async=false&network=true
    and: nio://127.0.0.1:57496 <http://127.0.0.1:57496> due to:
    java.net.ConnectException: Connection refused: no further information

    As a first troubleshooting step, we want to verify embedded broker
    is running on each server. Is there a way to verify the embedded
    broker is running?

    Thanks,

    Kevin
