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

             Summary: Need to expose offheap memory allocated size metric for internal data structures
                 Key: IGNITE-4797
                 URL: https://issues.apache.org/jira/browse/IGNITE-4797
             Project: Ignite
          Issue Type: Improvement
            Reporter: Andrey Gura
             Fix For: 2.0


Offheap caches expose offheap memory allocated size via {{CacheMetricsMXBean.getOffHeapAllocatedSize()}}. But this metric doesn't take into account offheap memory that allocated for internal data structures (GridUnsafeMap and LRU eviction policy).

However Ignite collects this metric (see GridUnsafeMemory.systemAllocatedSize() method).

Need to expose this metric via {{CacheMetricsMXBean}}.
