When discussing Application Performance Monitoring, which component of APM helps track whether errors get fixed or reappear?

The component of Application Performance Monitoring that focuses specifically on tracking errors, including whether they get fixed or reappear, is Exception Tracking. This aspect of APM allows developers and operations teams to monitor exceptions in their applications, offering insights into error frequency, types of exceptions, and context surrounding these issues. It provides vital information that assists in diagnosing problems, understanding their root causes, and ensuring that fixes are effective over time. By collecting detailed data on errors, Exception Tracking enables teams to see trends and improvements or recurrences of issues, which is essential for maintaining application health and performance.

In contrast, Distributed Tracing is more about understanding the flow of requests through multiple services, Synthetics focuses on simulating user actions to monitor application behavior, and Real User Monitoring captures the experience of actual users interacting with the application. While these elements contribute significantly to overall performance monitoring, they do not specifically concentrate on tracking the status of errors in the application like Exception Tracking does.
