The initial implementation of statistics isn't region based. I don't know if there's a JIRA issue for this yet but it's certainly a feasible enhancement.
Thanks for your reply..It's very much required for my project. Can you please tell me how to start with this enhancement in jboss cache codebase?
Statistics are generated by cache interceptors. See org.jboss.cache.interceptors.*. Generally, each interceptor maintains its own statistics (e.g., CacheLoaderInterceptor maintains cache loading statistics). CacheMgmtInterceptor maintains statistics for the cache itself (e.g., hits, misses).
