    • areaUnderCurve

      public static double areaUnderCurve(Class<? extends AbstractMetric> metricType, long skipNanos, long duration, boolean logScale)
      Calculate the area delimited between y = 0 and the given metric, in range [referenceTime+skipNanos, referenceTime+skipNanos+duration] Should be extremely fast, with O(n) complexity, being N the number of data points for the given metric.
      Parameters:
      metricType - metric type
      skipNanos - ignore any datapoint whose timestamp is less than (referenceTime+skipNanos).
      duration - pick only data points in range [referenceTime+skipNanos, referenceTime+skipNanos+duration]. Range is inclusive.
      logScale - Scale area under curve using natural logarithm
      Returns:
      area calculation as a double value
      Throws:
      IllegalArgumentException - if the area is unbounded or if the metric does not contain at least 1 datapoint.
