Original flame graphs use random colors to help visually differentiate adjacent frames. Variations include inverting the y-axis (an "icicle graph"), changing the hue to indicate code type, and using a color spectrum to convey an additional dimension. Flame graphs are both a …

Flame graphs can be created in three steps: 1. Capture stacks. Stack samples can be captured using Linux perf_events, FreeBSD pmcstat (hwpmc), DTrace, SystemTap, and many other profilers. See the stackcollapse-* converters.

A flame graph visualizes a distributed request trace and represents each service call that occurred during the request’s execution path with a timed, color-coded, horizontal bar. Flame graphs for distributed traces include error and latency data to help developers identify and fix bottlenecks in their applications.

Sep 23, 2023 · Flame charts and flame graphs are just two of many ways to visualize profiling data. They are useful in different scenarios, but they both have similar weaknesses too.

Oct 22, 2024 · The Flame Graph helps you identify hot paths in your code by showing a visualization of the call tree. The hot path is the call stack for the functions that are using the most CPU or the most time, and is often a good place to look for potential performance optimizations.

Aug 24, 2021 · Flamegraphs are the industry-standard way to visually represent runtime code stack traces and their respective time to execute as a hierarchy. These graphs are designed to help engineers quickly identify bottlenecks and frequently run codepaths. Below is an example Flamegraph produced by the Chromium Profiler: Consider the following functions:

Flame graphs are a visualization for sampled stack traces, which allows hot code-paths to be identified quickly. See the Flame Graphs main page for uses of this visualization other than CPU profiling.

Mar 28, 2023 · Flame graphs and icicle graphs are a great way to visualize performance profiles. In this post, we will learn how to read and interpret them.

Mar 20, 2025 · What is a Flame Graph? A Flame Graph is a visual representation of software stack traces, portraying the execution flow of a program. 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.

Sep 26, 2023 · Since I’ve been focused on visuals for code, I can’t leave out flame graphs for several reasons: A) they look really cool and B) they are one of the most helpful visualizations out there, and C) you can generate them for a shockingly wide number of use cases.
