Splunk configuration files are files used by Splunk to control its behavior and settings. These files define how Splunk processes data, indexes data, and provides access to various features and functionalities. The configuration files are typically written in plain text and are located in the Splunk installation directory, specifically in the "etc" directory.

4. outputs.conf: The outputs.conf file specifies the destinations where Splunk sends its processed data. It defines settings for forwarding data to other Splunk instances, third-party systems, or storage solutions.
5. indexes.conf: This file is used to configure and manage indexes in Splunk. It allows you to define properties such as index size limits, retention policies, access controls, and other index-specific settings.
