Adds an IMPACT label to an anomaly if the sum of the differences between predictions and observed values on a window containing the anomaly is less than a given threshold. Intuitively, it is the sum of impacts in the last n points.


  • The output of the detector. Labels are applied to the anomalies of this input.

namedescriptiondefault value
component.thresholdIf the sum of anomalies impact is below this threshold, label the anomaly.-1 (special value - no threshold)
component.windowWindow to compute the impact. In ISO-8601 (opens in a new tab) format.
component.impactComputationMethodMethod to compute the impact. STANDARD_AREA or ABSOLUTE_AREA. See below.STANDARD_AREA
component.monitoringGranularityGranularity of the timeseries in ISO-8601 (opens in a new tab) format. Should be same value as in the detector configuration.


    impact = sum(actual-expected) on the window
    impact = sum(abs(actual-expected)) on the window
