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.

Deploying Splunk in Docker

In this section, we will install a small distributed Splunk deployment, including a standalone Splunk instance and one forwarder. Ensure that you have the proper system requirements to install Docker, as listed at https://docs.docker.com/engine/install/, then install Docker on your host machine. We will rely heavily on the instructions provided by the Docker-Splunk documentation (https://splunk.github.io/docker-splunk/) in this section.

Figure 12.2 shows the setup that we will deploy:

Let’s install Splunk in Docker using the following steps:

  1. Install the latest Splunk Docker container from Docker Hub by using the docker command and specifying splunk:latest (latest full Splunk Enterprise) or universalforwarder:latest (latest Splunk Universal Forwarder):
    $docker pull splunk/splunk:latest
    $docker pull splunk/universalforwarder:latest
  2. Create a Docker network...
