Inferno is a set of tools that let you to produce flame graphs from performance profiles of your application. It’s a port of parts Brendan Gregg’s original flamegraph toolkit that aims to improve the performance of the original flamegraph tools and provide programmatic access to them to facilitate integration with other tools (like not-perf).Flame graphs have become an industry standard for CPU performance analysis. This visualization excels at showcasing the distribution of a sample (percentage of time a stack was on CPU) with hierarchical structure (call stack depth). However, flame graphs have seen sparse adoption outside of performance related use cases [1].

oracle cloud hcm Flame graphs. Flame graphs are a CPU profiling visualization technique that helps to spot at glance the most frequently used function, and most importantly the time they need to run.
