Anomaly Detection Techniques in Focus: Multivariate and Univariate Anodot

In our previous post, we explained what time series data is and provided some details as to how the Anodot time series anomaly detection system is able to spot anomalies in time series data. We also discussed the importance of choosing a model for a metric's normal behavior which included any and all seasonal patterns in the metric, and the specific algorithm which Anodot uses to find seasonal patterns. At the end of that post we said it's possible to get a sense of the bigger picture from a lot of individual anomalies. Conciseness is a requirement of any large-scale anomaly detection system because monitoring millions of metrics is guaranteed to generate a flood of reported anomalies, even if there are zero false positives. Achieving conciseness in this context is analogous to distilling the many individual symptoms into a single diagnosis, in much the same way that a mechanic might diagnose a car problem by observing the pitch, volume, and duration of all the sounds it makes, in addition to watching all the dials and indicator lights on the dashboard.
