Summary

The Continuous Profiler team at Datadog aims to make profiling a standard practice for all developers by making it more accessible and easier to interpret. To achieve this, they have introduced several enhancements to their flame graph visualization, including a new color coding scheme that makes it easier to understand resource usage patterns. The team has also simplified the ordering of frames and exposed menu selectors above the flame graph to serve as a legend. Additionally, they have introduced call graphs, which visualize method calls and their impact on resources in a way that highlights relationships among methods and their cumulative effect on resource usage. These new visualizations aim to make profiling data more approachable for less experienced engineers while preserving functionality for experienced users.
