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.

Monitoring Elasticsearch 5 rebranded its suite of monitoring tools, including the Elasticsearch-Logstash-Kibana (ELK) stack, in Elasticsearch 5. Marvel is now renamed Monitoring and comes bundled with some additional monitoring tools. The ELK stack is now just the Elastic Stack.

The Elasticsearch X-Pack is a premium suite of monitoring tools that charges an annual fee for running in production. The X-Pack consists of the following tools:

  • Monitoring: Previously Marvel

  • Shield: Adds authentication, access control, and HTTPS support to Elasticsearch

  • Watcher: Similar to Nagios, but with some Elasticsearch-specific features, such as sending email alerts if a query runs slow

  • Graph: Network-graph data visualization tool

  • Reporting: Generates PDF reports based on data in Kibana

Kibana and Marvel also received an updated look and feel, as seen in the following screenshots:
