What feature in Dynatrace allows code-level visibility?

The feature in Dynatrace that provides code-level visibility is method-level tracing using PurePath. This capability allows users to gain insights into individual method calls within an application, enabling them to see how different components interact and the performance of each method. By capturing detailed information about each request's journey through the various layers of the application, PurePath provides a clear view of performance bottlenecks, errors, and the overall health of the application at a granular level. This detailed tracing is crucial for developers and engineers as it helps in troubleshooting issues effectively and improving application performance based on real-time data.

The other options, while valuable in their respective contexts, do not directly provide code-level visibility. Instance monitoring focuses on the overall performance of infrastructure components, service lifecycle management pertains to overseeing the state and performance of services, and automated deployment tracking helps monitor changes and their impacts in the deployment pipeline. None of these options provide the same depth of visibility into individual code execution as PurePath does.
