Overview of this book

Elastic Stack, previously known as the ELK stack, is a log analysis solution that helps users ingest, process, and analyze search data effectively. With the addition of machine learning, a key commercial feature, the Elastic Stack makes this process even more efficient. This updated second edition of Machine Learning with the Elastic Stack provides a comprehensive overview of Elastic Stack's machine learning features for both time series data analysis as well as for classification, regression, and outlier detection. The book starts by explaining machine learning concepts in an intuitive way. You'll then perform time series analysis on different types of data, such as log files, network flows, application metrics, and financial data. As you progress through the chapters, you'll deploy machine learning within Elastic Stack for logging, security, and metrics. Finally, you'll discover how data frame analysis opens up a whole new set of use cases that machine learning can help you with. By the end of this Elastic Stack book, you'll have hands-on machine learning and Elastic Stack experience, along with the knowledge you need to incorporate machine learning in your distributed search and data analysis platform.

Understanding alerting concepts

Hopefully, without running the risk of being overly pedantic, a few declarations can be made here about alerting and how certain aspects of alerting (especially with respect to anomaly detection) are extremely important to understand before we get into the mechanics of configuring those alerts.

Anomalies are not necessarily alerts

This needs to be explicitly said. Often, users who first embrace anomaly detection feel compelled to alert on everything once they realize that you can alert on anomalies. This is potentially a really challenging situation if anomaly detection is deployed across hundreds, thousands, or even tens of thousands of entities. Anomaly detection, while certainly liberating users from having to define specific, rule-driven exceptions or hardcoded thresholds from alerts, also has the potential to be deployed broadly across a lot of data. We need to be cognizant that detailed alerting on every little anomaly could be potentially...
