Is there a way for mod_cluster_manager to show the clusters that workers are members of ? I'm thinking that, when we start node1, node2 and node3 which are part of the same cluster, that it would be nice to show that in mod_cluster_manager, maybe through invoking a method. Reason: when we start up multiple nodes, we don't know whether they actually formed a cluster. This can be seen via JMX, but the information is buried, and it would be nicer to see this in mod_cluster_manager.

A domain shows that it has node1, node2, node3, but that doesn't necessaily mean that node[1-3] really formed a cluster !

The information should also show the node in the cluster, e.g. Node1: Balancer: mycluster,Domain: dom1,cluster: cluster0 [Node1,Node2] Node2: Balancer: mycluster,Domain: dom1,cluster: cluster0 [Node1,Node2] We should make sure though that mod_cluster_manager doesn't get overloaded with this information... node names can get long ! > Correct? ... How could we get that information? In the STATUS MCMP? Brian, Paul ?

Yes - agreed, but it'll take time to get this into JON, so meanwhile it would be nice to have something in mod_cluster_manager
