    • Method Detail

      • getMetered

        Object getMetered()

      • rateUnit

        TimeUnit rateUnit()
        Returns the meter's rate unit.
        Returns:
        the meter's rate unit

      • eventType

        String eventType()
        Returns the type of events the meter is measuring.
        Returns:
        the meter's event type

      • count

        long count()
        Returns the number of events which have been marked.
        Returns:
        the number of events which have been marked

      • fifteenMinuteRate

        double fifteenMinuteRate()
        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

      • fiveMinuteRate

        double fiveMinuteRate()
        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

      • meanRate

        double meanRate()
        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

      • oneMinuteRate

        double oneMinuteRate()
        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
