Overview of this book

ElasticSearch is a distributed search server similar to Apache Solr with a focus on large datasets, a schema-less setup, and high availability. This schema-free architecture allows ElasticSearch to index and search unstructured content, making it perfectly suited for both small projects and large big data warehouses with petabytes of unstructured data. This book is your toolkit to teach you how to keep your cluster in good health, and show you how to diagnose and treat unexpected issues along the way. You will start by getting introduced to ElasticSearch, and look at some common performance issues that pop up when using the system. You will then see how to install and configure ElasticSearch and the ElasticSearch monitoring plugins. Then, you will proceed to install and use the Marvel dashboard to monitor ElasticSearch. You will find out how to troubleshoot some of the common performance and reliability issues that come up when using ElasticSearch. Finally, you will analyze your cluster’s historical performance, and get to know how to get to the bottom of and recover from system failures. This book will guide you through several monitoring tools, and utilizes real-world cases and dilemmas faced when using ElasticSearch, showing you how to solve them simply, quickly, and cleanly.

About the Author
About the Reviewers


This chapter gave you an overview of Elasticsearch and why it's important to proactively monitor a cluster. To summarize the points from the chapter:

  • Elasticsearch is an open source scalable, fast, and fault-tolerant search engine

  • Elasticsearch is built on top of Apache Lucene, the same library that powers Apache Solr

  • Monitoring tools will help us get a better understanding of our cluster and will let us know when problems arise

  • As helpful as monitoring tools are, it's up to us to actually diagnose and fix cluster issues

In the next chapter, we'll cover how to get a simple Elasticsearch cluster running and loaded with data, and how to install several monitoring tools.
