Elasticsearch 8.x Cookbook - Fifth Edition

By: Alberto Paro

Overview of this book

Elasticsearch is a Lucene-based distributed search engine at the heart of the Elastic Stack that allows you to index and search unstructured content with petabytes of data. With this updated fifth edition, you'll cover comprehensive recipes relating to what's new in Elasticsearch 8.x and see how to create and run complex queries and analytics. The recipes will guide you through performing index mapping, aggregation, working with queries, and scripting using Elasticsearch. You'll focus on numerous solutions and quick techniques for performing both common and uncommon tasks such as deploying Elasticsearch nodes, using the ingest module, working with X-Pack, and creating different visualizations. As you advance, you'll learn how to manage various clusters, restore data, and install Kibana to monitor a cluster and extend it using a variety of plugins. Furthermore, you'll understand how to integrate your Java, Scala, Python, and big data applications such as Apache Spark and Pig with Elasticsearch and create efficient data applications powered by enhanced functionalities and custom plugins. By the end of this Elasticsearch cookbook, you'll have gained in-depth knowledge of implementing the Elasticsearch architecture and be able to manage, search, and store data efficiently and effectively using Elasticsearch.

Chapter 11: User Interfaces

In an Elasticsearch ecosystem, it can be immensely useful to monitor nodes and clusters in order to manage and improve their performance and state.

Detecting malfunction or bad performance can be done through the API or through some frontends that are designed to be used in Elasticsearch.

Some of the frontends introduced in this chapter will allow you to have a working web dashboard in your Elasticsearch data; these work by monitoring cluster health, backing up or restoring your data, and allowing test queries before implementing them in the code. In this chapter, we will only briefly examine these frontends; this is due to their complexity and the large number of features, which are beyond the scope of this book. For an in-depth description, I suggest that you have a look at the official documentation of Kibana, which is available at https://www.elastic.co/guide/en/kibana/current/index.html.

In this chapter, we will explore some aspects of Kibana...
