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.

Exploring more Splunk commands

There are six types of commands in Splunk: distributable streaming, centralized streaming, generating, transforming, orchestrating, and dataset processing commands. In some cases, the way a command functions depends on where it is in the search. We will explore the different types of commands in the following subsections.

Streaming commands

We covered eval, fields, regex, and rex in Chapter 4, Introduction to SPL. These commands are streaming commands – that is, they are executed on the results of a search. There are two types of streaming commands:

  • Distributed streaming: Runs on the indexer or the search head. We will look at the rename command in this section.
  • Centralized streaming: Runs only on the search head. We will look at the head command in this section.

The rename command is an example of a distributed streaming command. It is used to rename fields. It is very useful for situations where the field names are long...
