Every Sentinel event or correlated event has certain fields that are automatically populated (such as Event Time and Event UUID) and other fields that may or may not be populated, depending on the type of event, the collector parsing, and the mapping service configuration. This event data is visible in Active Views, historical queries, and reports. They are stored in the database and can be accessed via the report views. They can also be used in actions available through the right-click event menu, correlation actions, and iTRAC workflow actions.
