public final class ChangeThresholdCondition

Type that describes change-threshold parameters. In change-threshold mode, metrics advisor watch for any data points that changes over a change percentage compared to the previous data points and detect such data points as anomalies.

Constructor Details

ChangeThresholdCondition

public ChangeThresholdCondition(double changePercentage, int shiftPoint, boolean isWithinRage, AnomalyDetectorDirection detectorDirection, SuppressCondition suppressCondition)

Create an instance of ChangeThresholdCondition describing how to identify anomalies using change-threshold mode.

Parameters:

changePercentage - the percentage of change that will considered as an anomaly, the data point will be compared with previously captured data points for computing the change.

shiftPoint - the number of data points that detector should look back for comparison.

isWithinRage - when set to true, data point is an anomaly when the value falls in the range; in this case, detectorDirection must be Both. When set false, the data point is an anomaly when the value falls out of the range.

detectorDirection - must be BOTH when isWithinRage is true. When isWithinRage is false, An UP value indicates that the data point should be considered as an anomaly, if its changes (compared to previous data points) more than the changePercentage. DOWN value means a data point should be considered as anomaly, if the change (compared to previous data points) falls below negated changePercentage value.

suppressCondition - the condition to aggregate the anomaly detection reporting, suppressing the reporting of individual anomalies helps to avoid noises, especially if the metrics have fine granularity.

Method Details

getAnomalyDetectorDirection

public AnomalyDetectorDirection getAnomalyDetectorDirection()
