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.

Adding inputs, tokens, and drilldowns

One of the advantages of Splunk is the ability to search through data. So far, we have created static dashboards. In this section, we will add inputs that will allow us to create filters for the data. We can add several different inputs to the dashboard, including the following:

  • Text
  • Radio buttons
  • Dropdowns
  • Checkboxes
  • Multiselect dropdowns
  • Link lists
  • Time pickers
  • Submit buttons

Follow these steps to create a new Text filter:

  1. Clicking on the Add Input dropdown at the top of the dashboard while in Edit mode gives you a list of all the available options (see Figure 7.12):

Let’s start with a new text box field for the IIS Logs dashboard panel.

  1. Click on the Add Input dropdown and select Text. A new input field called field1 will be added to the dashboard, as shown in Figure 7.13:
