Overview of this book

Splunk 9 improves on the existing Splunk tool to include important features such as federated search, observability, performance improvements, and dashboarding. This book helps you to make the best use of the impressive and new features to prepare a Splunk installation that can be employed in the data analysis process. Starting with an introduction to the different Splunk components, such as indexers, search heads, and forwarders, this Splunk book takes you through the step-by-step installation and configuration instructions for basic Splunk components using Amazon Web Services (AWS) instances. You’ll import the BOTS v1 dataset into a search head and begin exploring data using the Splunk Search Processing Language (SPL), covering various types of Splunk commands, lookups, and macros. After that, you’ll create tables, charts, and dashboards using Splunk’s new Dashboard Studio, and then advance to work with clustering, container management, data models, federated search, bucket merging, and more. By the end of the book, you’ll not only have learned everything about the latest features of Splunk 9 but also have a solid understanding of the performance tuning techniques in the latest version.

Discussing Splunk licensing models

We have got this far in the book without thinking about licenses. This is because the basic Splunk functionality can be appreciated using the free version of Splunk. Splunk Free is the implicit license that allows us to index 500 MB of data, run Splunk search queries, and create dashboards and reports. Splunk Free does not expire but only allows access to a limited number of Splunk Enterprise features. For example, Splunk Free does not allow for features such as clustering and will halt searching if there are license violations (three license warnings in a rolling 30-day window). Note that the AWS instances we created in Chapter 2, Setting Up the Splunk Environment, were not Splunk Free. The Splunk Enterprise AWS instances that we used are shipped with fully featured trial licenses, which are valid for 60 days. The license defaults to Splunk Free after the trial period.

Some of the other limitations of Splunk Free include the following:
