----------------------------------

             Summary: Provide JMX operation which shows the numberOfEntries in the entire dist-cache
                 Key: ISPN-3604
                 URL: https://issues.jboss.org/browse/ISPN-3604
             Project: Infinispan
          Issue Type: Feature Request
          Components: JMX, reporting and management
    Affects Versions: 6.0.0.CR1
         Environment: Max OS-X 10.8.5, Oracle Hotspot 1.7.0_40, Infinispan 5.2.4.Final
            Reporter: Duncan Doyle
            Assignee: Mircea Markus


The Infinispan statistics component only shows the 'numberOfEntries' in a particular node, including entries of which the node is not the primary owner (basically, doing a sum of this value of all the cluster members gives you (numberOfEntries * numOwners). The 'cache.keySet()' method does return the entire keyset, and thus you can calculate the numberOfEntries in the cache, but this requires writing custom code in a cache client. It would be nice if Infinispan would provide a JMX operation which is able to show the number of entries in the entire dist-cache cluster.
