    • count

      double count()
      Returns:
      The total number of occurrences of the timed event.

    • totalTime

      double totalTime​(java.util.concurrent.TimeUnit unit)
      The total time of all occurrences of the timed event.
      Parameters:
      unit - The base unit of time to scale the total to.
      Returns:
      The total time of all occurrences of the timed event.

    • mean

      default double mean​(java.util.concurrent.TimeUnit unit)
      Parameters:
      unit - The base unit of time to scale the mean to.
      Returns:
      The distribution average for all recorded events.

    • baseTimeUnit

      java.util.concurrent.TimeUnit baseTimeUnit()
      Returns:
      The base time unit of the timer to which all published metrics will be scaled

    • measure

      default java.lang.Iterable<Measurement> measure()
      Description copied from interface: Meter
      Get a set of measurements. Should always return the same number of measurements and in the same order, regardless of the level of activity or the lack thereof.
      Specified by:
      measure in interface Meter
      Returns:
      The set of measurements that represents the instantaneous value of this meter.
