WARNING: This documentation covers Elasticsearch 2.x. The 2.x versions of Elasticsearch have passed their EOL dates. If you are running a 2.x version, we strongly advise you to upgrade.
This documentation is no longer maintained and may be removed. For the latest information, see the current Elasticsearch documentation.
The majority of this book is aimed at building applications by using Elasticsearch as the backend. This section is a little different. Here, you will learn how to manage Elasticsearch itself. Elasticsearch is a complex piece of software, with many moving parts. Many APIs are designed to help you manage your Elasticsearch deployment.
In this chapter, we cover three main topics:
- Monitoring your cluster’s vital statistics, understanding which behaviors are normal and which should be cause for alarm, and interpreting various stats provided by Elasticsearch
- Deploying your cluster to production, including best practices and important configuration that should (or should not!) be changed
- Performing post-deployment logistics, such as a rolling restart or backup of your cluster
