Getting Started with Elastic Stack 8.0

By: Asjad Athick

Overview of this book

The Elastic Stack helps you work with massive volumes of data to power use cases in the search, observability, and security solution areas. This three-part book starts with an introduction to the Elastic Stack with high-level commentary on the solutions the stack can be leveraged for. The second section focuses on each core component, giving you a detailed understanding of the component and the role it plays. You’ll start by working with Elasticsearch to ingest, search, analyze, and store data for your use cases. Next, you’ll look at Logstash, Beats, and Elastic Agent as components that can collect, transform, and load data. Later chapters help you use Kibana as an interface to consume Elastic solutions and interact with data on Elasticsearch. The last section explores the three main use cases offered on top of the Elastic Stack. You’ll start with a full-text search and look at real-world outcomes powered by search capabilities. Furthermore, you’ll learn how the stack can be used to monitor and observe large and complex IT environments. Finally, you’ll understand how to detect, prevent, and respond to security threats across your environment. The book ends by highlighting architecture best practices for successful Elastic Stack deployments. By the end of this book, you’ll be able to implement the Elastic Stack and derive value from it.

Setting up your environment

In this section, we will explore the use of Elastic Agent and Fleet to easily onboard and manage how logs and metrics are collected from a sample application. To follow along with these examples, you will need access to the following:

  • An Elastic Stack deployment with Fleet to ingest and consume the data you collect from the application. You can choose to use Elastic Cloud to satisfy this requirement or provision a standalone deployment on a virtual machine.
  • A virtual machine to deploy your sample workload and an instance of Elastic Agent to collect data from.

Preparing your Elasticsearch deployment for Fleet

In Chapter 2, Installing and Running the Elastic Stack, we explored some of the options available for deploying Elasticsearch and Kibana. Fleet requires the use of API keys on Elasticsearch to authenticate and authorize the various agents that will be streaming data into Elasticsearch. As such, your Elasticsearch deployment needs...
