Ramesh Reddy commented on TEIID-2404:
-------------------------------------
# reads from disk = BufferFrontedCacheStore.getStorageReads
# writes to disk = BufferFrontedCacheStore.getStorageWrites
# disk space used = BufferServiceImpl.getUserBufferSpace
# Amount in soft cache, that can be reclaimed in gc = maxReserveBytes
I do not think I understand what it means by "BufferFrontedCacheStore concurrent bits set X block size."
I am not sure if knowing the # objects in memory is any good use.

> Project: Teiid
> Issue Type: Feature Request
> Components: Server
> Affects Versions: 8.3
> Reporter: Steven Hawkins

> Fix For: 8.3

> We should expose:
> BufferServiceImpl.getUserBufferSpace - the number of megs currently used by the buffermanager disk storage.
> A rough total of the memory buffer space used can be added, which would be from the BufferFrontedCacheStore concurrent bits set X block size.
> Also the BufferManagerImpl could report the total estimate of objects held in memory.
