Which feature of Splunk ES allows for real-time data visualization?

Dashboards in Splunk Enterprise Security (ES) are a powerful feature designed for real-time data visualization. They allow users to create a visual representation of data through graphs, charts, and tables, enabling quick insights into the information being processed. By aggregating and displaying data in an interactive format, dashboards facilitate the rapid interpretation and monitoring of security events as they occur.

Furthermore, dashboards can be customized to fit particular use cases, supporting real-time data feeds and providing users with the ability to apply filters and drill down into specific datasets. This makes them an essential tool for security analysts looking to maintain situational awareness and respond promptly to incidents as they arise.

While other options like event grouping, data models, and alerts play important roles in the functionality of Splunk ES, they do not specifically focus on real-time visualization in the way that dashboards do. Event grouping organizes related events, data models are structured frameworks for efficient data querying, and alerts are notifications triggered by specific conditions in the data, but none provide the comprehensive visual insights offered by dashboards.
