type Stats

type Stats struct {
	Average float64
	P99     float64 //99% percent process
	Max     float64
	Min     float64
	Period  int //in seconds
	Std     float64
}

func CalculateMetricStatisticsBasedOnDataAndPeriod

func CalculateMetricStatisticsBasedOnDataAndPeriod(data []float64, dataPeriod float64) Stats

CalculateMetricStatisticsBasedOnDataAndPeriod takes in an array of data and returns the average, min, max, p99, and stdev of the data. statistics are calculated this way instead of using GetMetricStatistics API because GetMetricStatistics would require multiple API calls as only one metric can be requested/processed at a time whereas all metrics can be requested in one GetMetricData request.
