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: 
2016-09-21 08:02:56,277 INFO [cluster.client] - Connecting...
2016-09-21 08:02:56,277 INFO [cluster.impl] - Using brokerURI: 

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.

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?

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 
2016-09-21 08:10:43,834 WARN [network.DiscoveryNetworkConnector] - Could not

nio://<> 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?
