      Starting with the standalone-full-ha.xml

      Set 'enable-statistics' to 'true' on the jgroups channel, transport (and all the protocols just to be sure, but they should default to the channel setting)

      Enable the Micrometer subsystem, using a wildcard to expose all subsystems. Added our OTLP collector endpoint.

      Observe that pushed JGroups metrics are all zero.

      At work we've got a Wildfly cluster using the 'standalone-full-ha' conifguration as a base. We'd like to have insight in the amount of traffic between Wildfly nodes, especially the amount of Infinispan cache invalidation traffic.

      I've enabled the Micrometer subsystem to push all subsystem metrics to out OTLP collector. This works for everything I've checked, except for the JGroups subsystem. Metrics are published, but are all set to zero. As far as I can see other subsystems push the correct metrics.
