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.

Learning how to use transforms

In this section, we are going to dive right into the world of transforming stream or event-based data, such as logs, into an entity-centric index.

Why are transforms useful?

Think about the most common data types that are ingested into Elasticsearch. These will often be documents recording some kind of time-based or sequential event, for example, logs from a web server, customer purchases from a web store, comments published on a social media platform, and so forth.

While this kind of data is useful for understanding the behavior of our systems over time and is perfect for use with technologies such as anomaly detection, it is harder to make stream- or event-based datasets work with Data Frame Analytics features without first aggregating or transforming them in some way. For example, consider an e-commerce store that records purchases made by customers. Over a year, there may be tens or hundreds of transactions for each customer. If the e-commerce...
