> HBase Canary reads once per column family per region. The current "region
> success count" should actually be "column family success count," which means
> we need another metric that actually reflects region success count.
> Additionally, the region read and write latencies only store the latencies of
> the last column family of the region read. Instead of a map of regions to a
> single latency value and success value, we should map each region to a list
> of such values.
