It offers a holistic view of system performance, condensing intricate stack trace data into a comprehensible format. Rectangular Frames: Each frame represents a function in the software stack.To color the frames in the flame graph by the function's metric consumption but exclude the metric consumption of its children, add a Color mode filter with the value of Self. For example, this filter shows that the baz function consumes more CPU time than any other function: What's next. Focus the flame graph on a function. View historical trends. Flame Graph. Flame Graphs are constructed by sampling stack traces a number of times.
