[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:all-tabpanel ]

Ramesh Reddy resolved TEIID-2404.
---------------------------------

    Resolution: Done


Couple other stats that are also part of this are the number of reads and writes into soft cache based store. The disk store is always fronted by soft referenced memory store, so, write to disk not necessarily correspond with read, as the content may be available in the soft-reference store.

> 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.
