What encapsulates the monitoring data sent via Dynatrace OpenKit?

The correct option encapsulates the monitoring data sent via Dynatrace OpenKit by referring to a custom application. Dynatrace OpenKit is designed to provide application performance monitoring and user experience insights specifically for applications that are developed by users or organizations. When you implement Dynatrace OpenKit, it enables you to instrument your custom application code to collect telemetry data such as user sessions, errors, and performance metrics.

By using a custom application as the encapsulating entity, you ensure that the specific application context is preserved, allowing Dynatrace to track performance and usage metrics that are uniquely associated with that application. This integration enables the identification of issues and understanding of user interactions in a way that is tailored to the specific behavior and structure of the application you are monitoring.
