      public static Stats create(Configuration configuration, AsyncInterceptorChain chain)
      Use this factory to create Stats object from configuration and the interceptor chain.
      Parameters:
      configuration -
      chain -
      Returns:
      Stats object

      collector -
      Returns:

    • getTimeSinceStart

      public long getTimeSinceStart()
      Specified by:
      getTimeSinceStart in interface Stats
      Returns:
      Number of seconds since cache started.

    • getTimeSinceReset

      public long getTimeSinceReset()
      Specified by:
      getTimeSinceReset in interface Stats
      Returns:
      Number of seconds since stats where reset

    • getApproximateEntries

      public long getApproximateEntries()
      Description copied from interface: Stats
      Returns the approximate number of entries in this cache that exist in memory or persistent storage. When the cache is configured with distribution, this method only returns the number of entries in the local cache instance. In other words, it does not communicate with other nodes to find out about data stored in the cluster and not available locally.
      Specified by:
      getApproximateEntries in interface Stats
      Returns:
      Number of entries currently in the cache, including passivated entries.

    • getApproximateEntriesInMemory

      public long getApproximateEntriesInMemory()
      Description copied from interface: Stats
      The same as Stats.getApproximateEntries(), however passivated entries are not included.
      Specified by:
      getApproximateEntriesInMemory in interface Stats

    • getApproximateEntriesUnique

      public long getApproximateEntriesUnique()
      Description copied from interface: Stats
      The same as Stats.getApproximateEntries(), however only entries owned as primary are counted. This is only different from Stats.getApproximateEntries() only in distributed and replicated caches.
      Specified by:
      getApproximateEntriesUnique in interface Stats

    • getCurrentNumberOfEntries

      public int getCurrentNumberOfEntries()
      Description copied from interface: Stats
      Returns the number of entries currently in this cache instance. When the cache is configured with distribution, this method only returns the number of entries in the local cache instance. In other words, it does not attempt to communicate with other nodes to find out about the data stored in other nodes in the cluster that is not available locally.
      Specified by:
      getCurrentNumberOfEntries in interface Stats
      Returns:
      Number of entries currently in the cache, including passivated entries.

    • getCurrentNumberOfEntriesInMemory

      public int getCurrentNumberOfEntriesInMemory()
      Description copied from interface: Stats
      The same as Stats.getCurrentNumberOfEntries(), however passivated entries are not included.
      Specified by:
      getCurrentNumberOfEntriesInMemory in interface Stats

    • getTotalNumberOfEntries

      @Deprecated(forRemoval=true) public long getTotalNumberOfEntries()
      Deprecated, for removal: This API element is subject to removal in a future version.
      Description copied from interface: Stats
      Number of entries stored in cache since the cache started running.
      Specified by:
      getTotalNumberOfEntries in interface Stats

    • getDataMemoryUsed

      public long getDataMemoryUsed()
      Description copied from interface: Stats

      Specified by:
      getDataMemoryUsed in interface Stats
      Returns:
      memory in use or -1 if memory eviction is not enabled

    • getOffHeapMemoryUsed

      public long getOffHeapMemoryUsed()
      Description copied from interface: Stats
      The amount of off-heap memory used by this cache, or -1 if the cache stores data in the heap.
      Specified by:
      getOffHeapMemoryUsed in interface Stats

    • getRetrievals

      public long getRetrievals()
      Specified by:
