[teiid-issues] [JBoss JIRA] (TEIID-2404) Expose buffermanager monitoring properties

[Ramesh Reddy (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-2404?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12756201#comment-12756201 ] 

Ramesh Reddy commented on TEIID-2404:
-------------------------------------

so,

Total Amount of memory in use = activBatchBytes + (initial maxReserveBytes) - maxReserveBytes

Amount of memory in use by active plans = (initial maxReserveBytes) - reserveBatchBytes 

What would be "blocksInUse.getBitsSet() * BLOCK_SIZE" represent? Is buffer memory used by FileStore?

> 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.
