>
> We've had this in our production for a while, and it's useful info to have.
> We already track FS read times in
> [HFileBlock|https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/io/hfile/HFileBlock.java#L1828-L1831C10].
> We can project that into the ScanMetrics instance and slow log pretty
> easily. It is also helpful to add a slow.fs.read.threshold, over which we log
> a warn
