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.

The username or ID is piped from an earlier part of the search and used as a key to access the additional information in the lookup. In this section, we will explore the use of the inputlookup and lookup commands. The inputlookup command is a generating command. It is usually used with a lookup file that contains Comma-Separated Values (CSV). The Splunk Settings menu contains a link to all the lookups stored in Splunk. The following steps will guide you and show you the lookups available in the Splunk Addon for Microsoft Windows, which we installed in Chapter 2, Setting...
