> 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.
