Flame Graphs # Flame Graphs are a visualization that effectively surfaces answers to questions like: Which methods are currently consuming CPU resources? How does consumption by one method compare to the others? Which series of calls on the stack led to executing a particular method? Flame Graph Flame Graphs are constructed by sampling stack traces a number of times. Each method call is presented by a bar, where the length of the bar is proportional to the number of times it is present in the samples.
