FlameCommander – Netflix’s Cloud Profiler
Simplifying the software profiling process and improving analysis with better visualizations is key to continuously improving the performance of your systems.
Even under constant load, the behavior of a system is affected by variance, perturbations, single-threaded execution and other time-based issues, and never completely uniform, making the analysis of these small variations a needle-in-a-haystack problem. FlameScope solved this problem by combining a subsecond-offset heatmap, for navigating a profile and visualizing these perturbations, with a flame graph for code-path analysis.
This talk focuses on how FlameScope, the open-source profile visualization tool, evolved into FlameCommander, a full-fledged cloud profiling solution used by thousands of engineers at Netflix.
