What feature allows users to visualize real-time data in Splunk?

The ability to visualize real-time data in Splunk is primarily enabled by the Live Tail feature. Live Tail is designed to provide instantaneous displays of streaming data as events occur, making it particularly useful for monitoring live logs and other data sources. This feature allows users to see new data flowing into Splunk as it happens, without the need to perform a traditional search or wait for a refresh.

While the Time Picker and Search Dashboard are important components for managing time ranges and displaying search results, they do not specifically cater to real-time data visualization. The Data Model primarily focuses on defining a structured framework for understanding complex datasets, which is more about organizing and optimizing data for searches rather than visualizing live data. In contrast, Live Tail directly addresses the need to view and analyze incoming data in real-time, making it the most suitable option for this purpose.
