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.

Forecasting use cases

In the context of Elastic ML, there are really just two—somewhat similar—use cases in which someone would use forecasting. These are outlined here:

  • Value-focused: This is where you extrapolate a time series into the future to understand a probable future value. This would be akin to answering questions such as: “How many widgets will I sell per day 2 months from now?”
  • Time-focused: This is where you understand the likely time at which an expected value is to be reached. This would answer questions similar to: “Do I expect to reach 80% utilization in the next week?”

The differences between these two use cases might not just be how a question is asked (how the data is searched), but also how you interpret the output. However, before we delve into a few examples of how to use the forecasting feature, let’s take a little time to discuss how it works logistically.
