Learning Elastic Stack 7.0 - Second Edition

By: Pranav Shukla, Sharath Kumar M N

Overview of this book

The Elastic Stack is a powerful combination of tools that help in performing distributed search, analytics, logging, and visualization of data. Elastic Stack 7.0 encompasses new features and capabilities that will enable you to find unique insights into analytics using these techniques. This book will give you a fundamental understanding of what the stack is all about, and guide you in using it efficiently to build powerful real-time data processing applications. The first few sections of the book will help you understand how to set up the stack by installing tools and exploring their basic configurations. You’ll then get up to speed with using Elasticsearch for distributed search and analytics, Logstash for logging, and Kibana for data visualization. As you work through the book, you will discover the technique of creating custom plugins using Kibana and Beats. This is followed by coverage of the Elastic X-Pack, a useful extension for effective security and monitoring. You’ll also find helpful tips on how to use Elastic Cloud and deploy Elastic Stack in production environments. By the end of this book, you’ll be well-versed with fundamental Elastic Stack functionalities and the role of each component in the stack to solve different data processing problems.

In this chapter, you learned how to use Elasticsearch to build powerful analytics applications. We covered how to slice and dice the data to get powerful insight. We started with metric aggregation and dealt with numerical datatypes. We then covered bucket aggregation in order to find out how to slice the data into buckets or segments, in order to drill down into specific segments.

We also went over how pipeline aggregations work. We did all of this while dealing with a real-world-like dataset of network traffic data. We illustrated how flexible Elasticsearch is as an analytics engine. Without much additional data modeling and extra effort, we can analyze any field, even when the data is on a big data scale. This is a rare capability that's not offered by many data stores. As you will see in Chapter 7, Visualizing Data with Kibana, Kibana leverages many of the aggregations...
