How do RUM and APM work together in Datadog?

RUM (Real User Monitoring) and APM (Application Performance Monitoring) work together in Datadog to provide a comprehensive view of user experiences and application performance. By integrating these two monitoring solutions, organizations can gain insights into user journeys and how those journeys correlate with application behavior.

RUM focuses specifically on the front-end performance as experienced by users in real time. It tracks metrics such as page load times, user interactions, and errors encountered by users in their browser or mobile application. This data allows teams to understand how well their application performs from the user's perspective.

On the other hand, APM is concerned with the backend performance of the application, such as server response times, database queries, and overall system health. By correlating the metrics from APM with the insights gained from RUM, teams can pinpoint not just where issues are happening, but also understand the cause of these issues in relation to the user experience.

This integration enables a more comprehensive analysis—examining both the user journey and the underlying application performance helps organizations identify performance bottlenecks, optimize user interactions, and ultimately enhance the overall user experience. In summary, the correct answer highlights how RUM and APM collectively improve visibility into user journeys, making it easier for teams to
