[The README says the metrics will look likeduration.acct.GET.200, but I don't see the "duration" in the code. I'm not sure what Etsy's server does, but our StatsD server turns timing metrics into 5 derivative metrics with new segments appended, so it probably works as coded. The first metric above would turn into acct.GET.200.lower, acct.GET.200.upper, acct.GET.200.mean ,acct.GET.200.upper_90, and acct.GET.200.count] - A counter increase by the bytes transferred for a metric like tfer.obj.PUT.201. > > Q3: What is StatsDlog?
