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 tables and charts to dashboards

We will start with a basic dashboard panel containing a table we created in Chapter 6, Creating Tables and Charts Using SPL. As a review, let’s complete the following steps:

    index=botsv1 earliest=0 sourcetype=iis
    | table _time, c_ip, s_ip, s_port, cs_uri_stem, cs_Referer, sc_status

This query displays IIS logs in the form of a table. Figure 7.1 shows the result of running this query:

Notice the Save As dropdown in the top-right corner of the search bar. This dropdown allows you the save the results of the query as a single report or as a dashboard panel. A Splunk report is the saved results of a single search. A Splunk dashboard can comprise several different objects, including reports, housed in one or more panels.
