Chapter 5. The Splunk Web Framework

In this chapter, we will dive directly into HTML dashboards and the Splunk Web Framework. This won't be just an overview, this is some serious coding. This is the nuts and bolts for all the newer apps being written and produced, as it provides the best options for customization and visualization. There is a basic structure, and some rather important points that need to be made, and some additional information on how to brand using custom CSS and JavaScript. We will explore the SplunkJS stack, and go over how the objects are used in their native form, and show how you can customize them. We will add a custom visualization using a D3 chart and place it in the dashboard. Using D3 charts allows for so much additional extensibility and presentation. We will also cover adding external data sources (via REST APIs and other methods) using the jQuery library.
