> Summarized block-cache report for a RegionServer would be helpful.  For example ...
> table1
>   cf1   100 blocks, totalBytes=yyyyy, averageTimeInCache=XXXX hours
>   cf2   200 blocks, totalBytes=zzzzz, averageTimeInCache=XXXX hours
> table2
>   cf1  75 blocks, totalBytes=yyyyy, averageTimeInCache=XXXX hours
>   cf2 150 blocks, totalBytes=zzzzz, averageTimeInCache=XXXX hours
> ... Etc.
> The current metrics list blockCacheSize and blockCacheFree, but there is no way to know
what's in there.  Any single block isn't really important, but the patterns of what CF/Table
they came from, how big are they, and how long (on average) they've been in the cache, are
important.
> No such interface exists in HRegionInterface.  But I think it would be helpful from an
operational perspective.
> Updated (7-29):  Removing suggestion for UI.  I would be happy just to get this report
on a configured interval dumped to a log file.
