What does configuring a 'Data Input' not involve?

Configuring a 'Data Input' in Splunk primarily focuses on how the data is received and processed within the platform. This includes specifying the data source, which entails identifying where the data is coming from, such as log files, network traffic, or API endpoints. Additionally, defining how data should be processed is crucial, as it determines how the incoming data will be indexed and stored in Splunk, impacting searchability and usability.

Determining the data format is also a critical aspect, as it ensures that Splunk correctly interprets the data structure and field values. This helps in accurately extracting relevant information for searches and reports.

Establishing user access levels, however, is not part of the data input configuration. Access levels are typically governed by user roles and permissions which are managed separately within the administration settings in Splunk. Therefore, focusing on data input configuration does not include user access considerations, making that option the correct choice.
