> As pointed out in https://cwiki.apache.org/confluence/display/GEODE/Enhance+Off-heap+memory+fragmentation+visibility:
> "Even though Geode offers several stats related to the status of the off-heap memory area ({_}usedMemory{_}, {_}freeMemory{_}, {_}fragmentation{_}, _largestFragment_ and {_}fragments{_}), the ones that provide information about the level of the fragmentation of the off-heap memory ({_}fragmentation{_}, _largestFragment_ and {_}fragments{_}) are only updated when defragmentation is executed."
> The visibility of the off-heap memory fragmentation status must be made more visible as proposed in the above RFC by means of:
>  * Updating the largestFragment stat periodically.
>  * Adding a new off-heap stat called "freedChunks" that will provide the number of elements in the tiny and huge lists. This stat will be periodically updated.
