By: Dr. Nadine Shillingford

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.

Introducing Splunk clusters

A Splunk cluster is a collection of Splunk Enterprise servers working together to ensure that data is available to users. Splunk search head and indexer clusters offer the following:

  • Protection against data loss (indexer clusters)
  • Data availability (search head and indexer clusters)
  • Fault tolerance (search head and indexer clusters)

Search head clusters ensure that the efficiency of a Splunk search is not affected as users and search volume increase. Indexer clusters store Splunk data in a form that ensures that indexes are replicated across members of the cluster.

In the next two sections, we will look at search head and indexer clusters. We’ll explore the role they play in ensuring data loss protection, data availability, and fault tolerance in Splunk deployments. There is also the concept of multisite clustering, where clusters are configured to exist across multiple geographical sites. However, this concept is beyond...
