Datadog's Continuous Profiler aims to make code profiling more accessible to engineers of all levels by introducing source code previews that contextualize profiling data, linking individual cells in flame graphs to relevant source code. To enable this feature, users need to set up Datadog's source code integration with their Git repositories and then hover over a flame graph cell to reveal the associated code. The preview also allows for more granular insights by grouping code lines instead of just methods, making it easier for engineers to troubleshoot performance issues in their applications.
