cache statistics via JMX

mircea.markus Aug 8, 2008 11:13 AM

Following information is currently being exposed through JMX:

1)RpcManager (replCount, replFailuresCount)
2)ActivationInterceptor (activation count)
3)CacheLoaderInterceptor (lods, misses)
4)CacheMngmtInterceptor (hits, missis, puts, eviction count, cache life in secs, avg read/write durration)
5)InvalidationInterceptor (number of invalidations)
6)PassivationInterceptor (number of passivations)
7) Txinterceptor (prepare, commit and rollback count)

Is there any other information you would find useful for being exposed?
( Starting with 3.0 it is much easier to aggregate/expose thorough JMX - JBCACHE-1305 )

BuddyManager - current group details (data owner name and buddies) as well as groups the current cache participates in, as a buddy.

RPCManager - channel information (configuration stack, bound address and port, JGroups View)

Cache configuration (read-only for non-@Dynamic fields, ability to modify for @Dynamic fields?)

Eviction queue status - but wait for JBCACHE-1141 for this.

LockManager - locks currently held? Essentially invoking LockManager.printLockInfo()?

Not sure whether this is already included in CacheMngmtInterceptor, but what about read/write percentages?

What about physical size of cache/regions? (I had someone asking this a short while back)

not exposed yet, good point

+1
we need to implement https://jira.jboss.org/jira/browse/JBCACHE-11 before being able to expose that one
