    Stats.getTotalNumberOfEntries() is it returns a wrong number?

    Kanitta Moonlapong Newbie

      I'm using a TreeCache API and would like to capture the number of node stores in cache.

       

      I've found the way to do that by using

      Stats stats = cacheManager.getCache(cacheInstanceName).getAdvancedCache().getStats();
      

       

      Actually, I have 300 keys store under /cacheName/groupName fqn

       

      The following are all statistics I got

      19:20:03,069 DEBUG InfinispanCacheManager:395 - ****************************************************************

      I wonder why I got 306? And after I insert a new key into the cache

       

      The statistics change to

      
      
      18:57:03,059 DEBUG InfinispanCacheManager:396 - |     [Statistic] cacheName     : menuCache
      18:57:03,060 DEBUG InfinispanCacheManager:398 - |     [Statistic] getAverageReadTime     : 0

      18:57:03,076 DEBUG InfinispanCacheManager:413 - |     [Statistic] getRemoveMisses     : 0
      18:57:03,076 DEBUG InfinispanCacheManager:415 - |     [Statistic] getRetrievals     : 2422     * Number of get operations

      18:57:03,079 DEBUG InfinispanCacheManager:427 - |     [Statistic] getTotalNumberOfEntries     : 307     *Number of entries stored in cache
      

       

      Why the number change corresponding to getStores number?

       

      Please, suggest and thank you in advance.
