[infinispan-issues] [JBoss JIRA] (ISPN-3604) Provide JMX operation which shows the numberOfEntries in the entire dist-cache

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: Duncan Doyle Fix For: 8.1.0.Final 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.
