In which configuration file are transforms defined?

Transforms are defined in the transforms.conf file, which is a critical configuration file in Splunk that deals specifically with data transformation processes. This file allows you to configure how incoming data should be altered or manipulated before it's indexed or during searching.

For instance, transforms.conf is used to define settings for field extraction, data formatting changes, and routing of events, among other data transformations. It works in conjunction with props.conf, which specifies how the data should be handled and which transformations to apply based on the source or event type.

Overall, transforms.conf plays a key role in shaping the data landscape within Splunk, enabling administrators to control and refine how data is processed and indexed, thus ensuring that you get the most relevant and useful information from your logs and events.
