      Description

      Currently Flink metric system supports counter, gauge, histogram and meter. For cases which involve measuring the latency of short-term events (such as request latency in the context of a connector), none of these metric types is a good fit. Most metric system supports a timer type which is highly useful in such cases. Timers are useful for measuring short-duration latencies and the frequency of such events. All implementations of Timer report at least the total time and count of events as separate time series.

      Timer type will be a nice addition to the existing metric types in Flink. We are happy to contribute it if there is agreement on it being a good addition.
