-------------------------------------
Assignee: Alberto Gomez
> Enhance Off-heap memory fragmentation visibility
> -------------------------------------------------
>
> Key: GEODE-10087
> URL: https://issues.apache.org/jira/browse/GEODE-10087
> Project: Geode
> Issue Type: Improvement
> Components: offheap, statistics
> Reporter: Alberto Gomez
> Assignee: Alberto Gomez
> Priority: Major
>
> 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.
