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`
