The Anomaly Detector service enables you to find abnormalities in your time series data by automatically using the best-fitting models on it, regardless of industry, scenario, or data volume. Use the Anomaly Detector client library for Python to: Detect anomalies throughout your time series data set, as a batch reques

Now build a classification model and get rules (classification model ) to identify abnormality at run time (time series data). If abnormalities are unknown , during my research, most common way of identifying abnormalities is to build a normal model and any deviation from normal model (error) is abnormal, so in your case, you forecast your time series for next hour and then compare with actual values Also, we are going to use a Python library called PyOD which is specifically developed for anomaly detection purposes. I really encourage you to take a look at the official documentation of PyOD here You can: in the 4th graph (residual plot) at Attempt 2 : Using Seasonal Decomposition try to check for extreme points and that may lead you to some anomalies in the seasonal series. Supervised (if you have some labeled data): Do some classification

Anomaly Detection Toolkit (ADTK) is a Python package for unsupervised / rule-based time series anomaly detection. As the nature of anomaly varies over different cases, a model may not work universally for all anomaly detection problems. Choosing and combining detection algorithms (detectors), feature engineering methods (transformers), and ensemble methods (aggregators) properly is the key to. Example of the **time** **series** with an **anomaly**. For example, it is okay, when the CPU load of some application is about 20%, but it seems strange when the load unexpectedly jumps to 80%. And one more important thing is that the load level around 80% after this jump is not suspicious anymore. That is why some threshold warning values can't handle such complex situations
