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.

Using federated search

Running federated searches varies, based on whether the federated provider is running in standard or transparent mode. Federated searches that run over transparent mode do not require any new syntax. These federated searches are run using the same syntax as regular local searches. However, federated searches executed on standard mode federated providers require additional syntax. If this syntax is not used, the search will be executed on the indexers in the local deployment only. Before we can run a federated search in standard mode, we must ensure that a user with the admin role creates federated indexes on the federated search head in the local deployment. Remember that this is a logical index and does not actually ingest data. In addition, you need to ensure that the knowledge objects in your search, such as lookups, are present both on the local search head and the federated search head on the remote deployment. The following examples show how to run federated...
