    • mark

      public void mark()
      Description copied from interface: Meter
      Records one occurrence.
      Specified by:
      mark in interface Meter

    • mark

      public void mark(long count)
      Description copied from interface: Meter
      Records events occurrences.
      Specified by:
      mark in interface Meter
      Parameters:
      count - Number of occurrences to record.

    • getCount

      public long getCount()
      Description copied from interface: Meter
      Returns the number of events.
      Specified by:
      getCount in interface Meter
      Returns:
      the number of events.

    • getMeanRate

      public double getMeanRate()
      Description copied from interface: Meter
      Returns the mean rate at which events have occurred since the meter was created.
      Specified by:
      getMeanRate in interface Meter
      Returns:
      the mean rate at which events have occurred since the meter was created

    • getOneMinuteRate

      public double getOneMinuteRate()
      Description copied from interface: Meter
      Returns the one-minute exponentially-weighted moving average rate at which events have occurred since the meter was created.

      This rate has the same exponential decay factor as the one-minute load average in the top Unix command.

      Specified by:
      getOneMinuteRate in interface Meter
      Returns:
      the one-minute exponentially-weighted moving average rate at which events have occurred since the meter was created

    • getFiveMinuteRate

      public double getFiveMinuteRate()
      Description copied from interface: Meter
      Returns the five-minute exponentially-weighted moving average rate at which events have occurred since the meter was created.

      This rate has the same exponential decay factor as the five-minute load average in the top Unix command.

      Specified by:
      getFiveMinuteRate in interface Meter
      Returns:
      the five-minute exponentially-weighted moving average rate at which events have occurred since the meter was created

    • getFifteenMinuteRate

      public double getFifteenMinuteRate()
      Description copied from interface: Meter
      Returns the fifteen-minute exponentially-weighted moving average rate at which events have occurred since the meter was created.

      This rate has the same exponential decay factor as the fifteen-minute load average in the top Unix command.

      Specified by:
      getFifteenMinuteRate in interface Meter
      Returns:
      the fifteen-minute exponentially-weighted moving average rate at which events have occurred since the meter was created
