Is there a way to verify whether the communication among the members of the cluster is healthy? For instance, there are 4 VMs each hosting a single JVM representing a member of the ModeShape cluster. I want to know whether each member is aware of others and that a message sent from one member gets propagated to others. So far, I have found methods [1] and [2] that look promising, but those are not publicly exposed [3] to the consuming applications. The reason I am looking for this kind of health check is because I want to incorporate it into the existing suite of health checks that can easily flag whether something wrong is happening. Any help is appreciated.
