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.

Setting up Splunk search heads

The last component that we will set up is the search head. Remember that the search head is how users access Splunk Web. Follow these steps:

  1. Log in to your deploymentserver instance using an SSH client. Refer to step 1 of the Setting up Splunk Deployment Servers section for information on logging in to SSH. Enter yes to the authenticity prompt:
    ssh -i "<your private key>.pem" ec2-user@<your EC2 Instance name or IPv4>

Use the sudo command to change from ec2-user to the splunk user:

sudo -i -u splunk

Use the following command to check that Splunk is running:

/opt/splunk/bin/splunk status
  1. Now, let’s set up our search head. First, we will start by changing the hostname and server name, as we did for the forwarders, deployment server, and indexer. Use the following command to change the hostname and server name:
    /opt/splunk/bin/splunk set servername searchhead
    /opt/splunk/bin/splunk set default-hostname...
