A Splunk add-on is a reusable component designed to provide specific capabilities, such as data collection or knowledge object mapping, to other apps. Each add-on is installed in its own directory under $SPLUNKHOME/etc/apps, which serves as its unique namespace within the Splunk instance, preventing naming conflicts. Add-ons can also be designed with dependencies on other add-ons. For example, a technology-specific add-on might require the Splunk Common Information Model (CIM) Add-on to be installed for proper data normalization and functionality. This modularity allows for building complex solutions by combining different components.

A. A navigation file (nav.xml) defines the user interface navigation bar. Add-ons typically lack a graphical user interface, so this file is not a requirement.

D. This statement describes a standalone app. Add-ons are specifically designed as reusable components intended to be used by other apps across the Splunk environment.

"Overview of Splunk apps and add-ons". This document distinguishes between apps and add-ons

stating

"An add-on is a type of app that provides specific capabilities to other apps... it is a reusable component that supports other apps." This supports the rejection of option D and the concept of dependencies (C).

"app.conf". The specification for app.conf under the [package] stanza details the dependencies setting

which allows an app or add-on to declare its dependency on other apps. This directly supports option C.

"Splunk app file structure". This section describes the required directory structure for any app or add-on

where the top-level directory name under etc/apps must be unique

establishing its namespace. This supports option B.
