      double getFiveMinuteRate()
      Returns the five-minute exponentially-weighted moving average rate at which events have occurred since the meter was created.
      double getMeanRate()
      Returns the mean rate at which events have occurred since the meter was created.

    • Method Detail

      • getCount

        long getCount()
        Returns the number of events which have been marked.
        Specified by:
        getCount in interface Counting
        Returns:
        the number of events which have been marked

      • getFifteenMinuteRate

        double getFifteenMinuteRate()
        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.

        Returns:
        the fifteen-minute exponentially-weighted moving average rate at which events have occurred since the meter was created

      • getFiveMinuteRate

        double getFiveMinuteRate()
        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.

        Returns:
        the five-minute exponentially-weighted moving average rate at which events have occurred since the meter was created

      • getMeanRate

        double getMeanRate()
        Returns the mean rate at which events have occurred since the meter was created.
        Returns:
        the mean rate at which events have occurred since the meter was created

      • getOneMinuteRate

        double getOneMinuteRate()
        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.

        Returns:
        the one-minute exponentially-weighted moving average rate at which events have occurred since the meter was created
