The configuration file that Splunk utilizes to control indexing behavior is Index.conf. This file is essential for defining settings that dictate how data is indexed, such as specifying which indexes to use, adjusting data retention policies, and managing index storage. It plays a critical role in optimizing performance and ensuring that data is stored in a manner appropriate for the user’s organizational needs.

While Inputs.conf is focused on the configuration of how data is ingested into Splunk, and Outputs.conf deals with how data is sent out from Splunk to other destinations, Props.conf is primarily concerned with data transformation and extraction of metadata during indexing. Each of these files serves a specific function, but only Index.conf directly manages index settings and behaviors, making it the key file for controlling indexing in Splunk.
