This page describes the metrics
outlier operator and how to use it in a metric query.
outlier operator identifies metrics data points that are outside the range of expected values. Outliers help you spot unusual behavior in your metrics visualizations and track the behavior over time.
outlier operator tracks the moving average and standard deviation of a time series, and calculates a threshold band that is 10 standard deviations above and below the moving average. Data points outside the threshold band are considered outliers.
