Re: [infinispan-dev] Setting JGroups channel name
If you don't define a logical name, JGroups will pick one for you. The
name will look like {hostname}-{randomShort}, e.g. mybox-12345.
I recommend a good logical name should include
- the function (e.g. "SessionReplication")
- the location (e.g. "mybox")
- if you have multiple instances running on the same box, maybe an ID
Example: SessionCache-mybox-33

Yes, but as soon as you have two cache managers in the same VM you are
screwed, right? We would end up with two channels with the same name.
Everything would work as far as JGroups is concerned but logs would be
useless.
Don't forget that channel names need to be unique per JVM and across JVMs!
The only solution I can think of is to add API that allows naming of
CacheManagers. That name could be reused to name channel as well.
