    Viewing replication activity

    doug smith Newbie

      Greetings,

      I am working with JBoss Cache as a second level hibernate cache, where Hibernate is used via Spring DAO support.

      By virtue of Hibernate logging I can tell the cache is working as expected, and that data is being replicated. However, I have not been able to figure out the right log settings to view the replication activity via the logs.

      Ideally, in a two JVM cluster, I'd like to see all activity related to replication in the logs (for my own edification) -- logging related to the 2 phase commit (for REPL_SYNC), logging related to data transfer, etc.

      I can glean the fact data is being replicated by setting the serialization logging to debug, but I'm really after a higher level picture of the communication between the cluster members. When replication is occurring, for example, I don't see any indication of JGroups activity.

      Here's my logging configuration (this is all running in the latest GA JBoss app server).
