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]
