ABSOLUTE_CHANGE
Compares current time series to a baseline. If the absolute change is above a certain threshold, detect it as an anomaly.
Inputs
"targetProperty": "current": The data on which to perform detection.
"targetProperty": "baseline": The data to use as a baseline.
The inputs should have the same size.
Parameters
| name | description | default value |
|---|---|---|
component.absoluteChange | The absolute change threshold. If the absolute change when compared to the baseline is above this threshold, detect an anomaly. | |
component.pattern | Detect as an anomaly if the metric drop, rise or both directions. UP, DOWN, UP_OR_DOWN. | UP_OR_DOWN |
