--------------------------------
Excellent! Feel free to reopen if you run into an issue when using this change.
Provide an overloaded JmxConfigurator.registerChannel that takes an
ObjectName to be used as prefix instead of the domain
-------------------------------------------------------------------------------------------------------------------------
Key: JGRP-2394
URL:
https://issues.jboss.org/browse/JGRP-2394
Project: JGroups
Issue Type: Enhancement
Affects Versions: 4.1.6
Reporter: Nistor Adrian
Assignee: Bela Ban
Priority: Major
Fix For: 4.1.8
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.
