The readRequestCount actually counts the number of rows returned from the region server with totals of all the hosted regions. The writeRequestCount counts the number of mutations/appends/increments with totals of all the hosted regions. The totalRequestCount is a mixed bag as Elliott mentioned, but does not cover the above two completely.
