public final class TopNGroupScope

The type TopNGroupScope represents the parameters that defines TopN anomaly scope. Detector produces an alert when such "scoped" anomalies are detected.

Each metric has a stream of data points. There can be multiple metrics, hence multiple streams of data points. When these multiple streams produce data points, it can be form a "set" stream. Each set (aka point-set) is indexed by a timestamp; such a set contains data points information arrived at that timestamp from different streams. The TopNGroupScope parameters defines the criteria to report anomalies from these point-set. Each data point in the point-set can be either an anomaly or not. Each anomaly has a rank assigned. The detector can look into the rank of anomalies in each point-sets and use them to compute anomaly-rank for the point-set. The Period in TopNGroupScope means how many latest point-sets we want the service to select for ranking. The Top in TopNGroupScope defines the top anomaly-rank (like top 3 rank), and when anomaly-rank of MinTopCount number of point-sets falls into this top rank, the detector to produce an alert.

Constructor Details

TopNGroupScope

public TopNGroupScope(int top, int period, int minTopCount)

Create an instance of TopNGroupScope describing parameters that defines TopN anomaly scope.

Parameters:

top - the top anomaly-rank.

period - the number of latest point-sets detector select for ranking.

minTopCount - the number of point-sets in the period to falls into the top rank for anomaly reporting.
