      Description

      Hi guys, 

          Currently, Flink only support 4 registering metrics, CountersGaugesHistograms and Meters.  If we want to measure the time cost metric, for example P75th, P99th, P999th, right now can only use Histograms metric. But Histograms metric not support TimeUnit type (second, millisecond, microsecond, nanosecond). So it's not convenient to collaborate with outside metric system. 

          The Codahale/DropWizard support Time meter, so we can wrap it in Flink. 

          Flink metrics doc https://ci.apache.org/projects/flink/flink-docs-master/monitoring/metrics.html
          Thanks for your time.
