> Reporter: Doug Meil

> I filled out the skeleton of the metrics in book.xml, but I'd like one of the
> committers to fill in the rest of the details on what these mean. Thanks! :-)
> For example..
> -------
> I'm assuming that these are referring to the LRU block cache in memory. I'd
> like to docs to state this (for the sake of clarity) and also the units
> (e.g., MB).
> hbase.regionserver.blockCacheCount
> hbase.regionserver.blockCacheFree
> hbase.regionserver.blockCacheHitRatio
> hbase.regionserver.blockCacheSize
> -------
> This is read latency from HDFS, I assume...
> hbase.regionserver.fsReadLatency_avg_time
> hbase.regionserver.fsReadLatency_num_ops
> hbase.regionserver.fsSyncLatency_avg_time
> hbase.regionserver.fsSyncLatency_num_ops
> hbase.regionserver.fsWriteLatency_avg_time
> hbase.regionserver.fsWriteLatency_num_ops
> ----------------
> point in time utilized (i.e., as opposed to max or trailing) memstore I
> assume, would be nice to document.
> hbase.regionserver.memstoreSizeMB
> ---------------
> obvious, but might as well document it
> hbase.regionserver.regions
> --------------
> This is any Put, Get, Delete, or Scan operation, I assume?
> hbase.regionserver.requests
> --------------
> detail on these would be nice, especially for tips on if there are any
> critical numbers/ratios to watch for.
