Flame graph.
Flame Graph. Flame Graphs visualize the performance of your application’s code. A Flame Graph shows the time spent in each part of your application’s call stack, where the width of the event is proportional to how long it takes to execute. Flame Graphs make it easy to see how much time is spent in each function, and which calls are the most ...
Red/Blue Differential Flame Graphs. I've had many discussions about this for years, and finally wrote an implementation that I hope makes sense. It works like this: Take stack profile 1. Take stack profile 2. Generate a flame graph using 2. (This sets the width of all frames using profile 2.) Colorize the flame graph using the "2 - 1" delta.Flame graphs also expose the impact of long-running functions on overall performance. While some functions, like renders to body, are intended to run longer, others such as support services and callbacks, should be optimized for efficiency. The graph’s tally of execution times offers a comprehensive overview, ensuring developers can focus ...

See CPU Profile for another example. ** Graphs in this case refers to the specific vertex+edge graphs of Graph Theory.On the other hand …A flame graph will give you the following information: Y-axis / Height: presents the stack depth. X-axis / Width: presents how much time (number of samples) was spent within a method. Color: depending on the configuration will e.g. highlight Java, C++, kernel methods. Important to note is that the X-axis != time passing.
20 Jan 2016. CPU profiles, which can be visualized as a CPU flame graph, can solve a wide range of CPU usage issues. Off-CPU analysis, which can be visualized as Off-CPU time flame graphs, can begin to solve the rest. As I recently hacked stack traces for eBPF, I can now start to explore off-CPU profiling using core Linux capabilities.Memory Flame Graph.
