// Package anomalyfinder implements the Azure ARM Anomalyfinder service API version 2.0.
//
// The Anomaly Finder API detects anomalies automatically in time series data. It supports two functionalities, one is
// for detecting the whole series with model trained by the timeseries, another is detecting last point with model
// trained by points before. By using this service, business customers can discover incidents and establish a logic
// flow for root cause analysis.
