The ehcache-1.x-remote-debugger.jar can be used to debug replicated cache operations. When started with the same configuration as the cluster, it will join the cluster and then report cluster events for the cache of interest. By providing a window into the cluster it can help to identify the cause of cluster problems.

From version 1.5 it is packaged in its own distribution tarball along with a maven module. It is provided as an executable JAR on the Ehcache download page.

This version of the debugger has been tested only with the default RMI-based replication.
