What type of data is typically NOT ingested by Splunk?

The type of data that is typically not ingested by Splunk is structured data only. Splunk is designed to handle a variety of data types, including log files and unstructured data, which are its primary strengths. It excels at indexing unstructured data like log files, events, metrics, and other non-hierarchical information, allowing users to search, analyze, and visualize that data easily.

Structured data, by definition, is highly organized and formatted in a way that is easily searchable in relational databases, such as tables with fixed fields. While Splunk can technically read and index structured data, it is primarily built for unstructured and semi-structured data, making it less suitable for ingestion where data is strictly structured. Thus, the classification of data as "structured only" does not accurately reflect the core capabilities and intended use of Splunk.
