Hello @Sangeetha M.
Within production environments, a single host, or even a single process, may include thousands of individual events. The Dynatrace event-analytics engine can process all such events, even over large analysis timeframes. Importantly, event analysis offers convenient drill-down and filtering options that make it easy to focus on specific points in time where high event activity occurred and then filter those events based on event type.
Have a look on the below link for scaling up and drilling down features understanding.
