Flame graph.

A flame graph takes advantage of the hierarchical nature of profiling data. It condenses data into a format that allows you to easily see which code paths are consuming the most system resources, such as CPU time, allocated objects, or space when measuring memory. Each block in the flame graph represents a function call in a stack and its width ...

Flame graph. Things To Know About Flame graph.

If this flame graph were derived from wall-time samples, rather than CPU-time samples, it could look more like the second graph below, which tells you where time actually goes: What was a big juicy-looking pile on the right has shrunk, so it is nowhere near as significant. On the other hand, the I/O towers are very wide.What's a flame graph useful for? Flame graphs are a way of visualizing CPU time spent in functions. They can help you pin down where you spend too much time doing …In this case, the graph height will be calculated automatically to fit the whole stack.
