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.

Improving performance

In this section, we will look at several best practices that can help improve our Splunk experience. We will explore useful backend and search time practices, including efficient search syntax, setting limits, and other interesting methods.

We can increase the efficiency of Splunk on the backend by implementing some simple configurations and practices:

  1. Follow the memory and CPU recommendations from Splunk. Refer to the current Splunk documentation to ensure that your servers meet Splunk’s recommendations.
  2. Ensure that the operating system supports the version of Splunk you plan to use. Universal forwarders work on a range of operating systems. However, the current Enterprise License only works on the latest Linux (x86 64- bit) kernel versions, Windows Server (2022, 2016, and 2019), and Windows 10 (x86 64-bit). Splunk also runs on AWS instances (as we saw in Chapter 2, Setting Up the Splunk Environment). Containerized solutions such as Docker...
