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.

Visualizing data with dashboards

Dashboards in Kibana are the primary tool to visualize datasets in order to understand what the data means. Users generally spend a significant chunk of their time on Kibana working with dashboards; well-designed dashboards can efficiently communicate important metrics, trends in activity, and any potential issues to look out for.

The Nginx dashboard shown in the following screenshot (available out of the box) visualizes source geo-locations, web server response codes over time, common error types, and top resources accessed on the web server. An engineer eyeballing this data can spot something out of the ordinary. If, for example, HTTP 5xx response codes suddenly start increasing for a given resource on the server, the engineer can quickly narrow down potential issues and proceed to fix them before end users are impacted:
