Anomaly Detector v1.1-preview.2

The Anomaly Detector service detects anomalies and trace root causes automatically in time series data. It supports several functionalities:

  • Detecting anomalies in single time-series, including entire, last and change point detection. With this univariate anomaly detection capability, business customers can discover incidents and establish a logic flow for root cause analysis.
  • Detecting anomalies in multiple time-series. This set of multivariate anomaly detection APIs in Anomaly Detector analyze dependencies and inter-correlation changes between different signals. It enables customers to gather a group of related time-series and detect failures in a system level.
  • Indicate root causes that contribute the most on an aggregated anomaly point. Accurate dimension can be drilled down for both one measure and multiple measures. Meaningful interpretation is also provided.

To ensure online service quality is one of the main reasons we developed this service. Our team is dedicated to continuing to improve the Anomaly Detector service to provide precise results.
