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.

For simplicity, we have collapsed the XML by clicking on the arrows next to the line numbers so that only the main tags are visible, as shown in Figure 7.30:

We can see that the source of the simple XML dashboard is enclosed in an outer pair of <form> tags:

<form>

The title and description that we assigned to the dashboard are enclosed within the <label> and <description> tags, respectively. Each of our three panels is enclosed in a pair of <row> tags. Let’s look at the first panel with the filters. All the inputs (text boxes, dropdown, and time picker) are enclosed in the ...
