[jboss-jira] [JBoss JIRA] (JGRP-2394) Provide an overloaded JmxConfigurator.registerChannel that takes an ObjectName to be used as prefix instead of the domain

Bela Ban commented on JGRP-2394:
--------------------------------

Why can't you use {{domain}} and/or {{clusterName}} to create unique registrations? These don't have to correspond to the real domain or cluster name.

> The JmxConfigurator.registerChannel variant that takes a domain is not enough for use cases where multiple apps running in a jvm join the same JGroups cluster and also share the same jmx domain. In this case the channel MBean object names will collide. The de-duplication mechanism using random number suffixes does not provide predictable results.  Avoiding jmx domain sharing is also not possible due to the nature of the use case.
> So we propose adding someting like this:
> JmxConfigurator.registerChannel(JChannel channel, MBeanServer server, ObjectName namePrefix,  String cluster_name, boolean register_protocols)
> which would allow the application using JGroups to have greater control of the generated object names for channel and protocols.  The namePrefix will provide the domain and also a key-value list that will serve as the prefix for all ObjectNames internally generated by JGroups. It will be the caller's task to ensure this leads to generation of unique names.
