These allow you to categorize events based on search terms. Select your answer.

Event types are user-defined knowledge objects in Splunk that classify events based on a search string. When an event matches the search criteria defined within an event type, Splunk tags that event with the corresponding event type name. This allows users to categorize and group disparate events that share common characteristics under a single, meaningful label. Using event types simplifies searching, reporting, and alerting by replacing complex search logic with a simple eventtype="" syntax, making data analysis more efficient and consistent.

The first paragraph states, "An event type is a categorization system that you can assign to events that share common characteristics. An event type is defined by a search that looks for a specific set of information in your data."

2. Splunk Enterprise Search Manual, Version 9.2.1, "Use event types in searches". This section details how to use the eventtype field in searches, explaining that it is a default field added to events that match an event type definition, thereby confirming its role as a search-based categorization tool.
