The most important things it shows are how much CPU each method used (since this is a CPU profile) and how each method was called. For example, reading from the second row from the top, you see that Thread.run() called QueuedThreadPool$2.run() (amongst other things), which called …I first summarized off-CPU time flame graphs in the later part of my USENIX LISA 2013 plenary, and more recently in my USENIX ATC 2017 talk, starting at 50:16 (youtube, slides). There are at least four approaches for analyzing off-CPU time with flame graphs, enumerated in figure 1 and explained in following sections.Generate flame graphs using the text files you dumped from DB: flamegraph.pl <INPUT_FILES> > <OUTPUT_FILES> Example. The following is an example of running and profiling a Spark application.Flamegraph generator for python’s cProfile stats. Flamegraphs allow to visualize relations between functions in a very compact and understandable manner.

This can be visualized as a flame graph, where the x-axis spans the total blocked time, and the flame graph shows the blocking code paths. As the entire profiler output is visualized at once, the end user can navigate intuitively to areas of interest. The shapes and locations in the flame graphs become visual maps for the execution of software.

The CPU flame graphs page explains how to interpret these, and this was created using the instructions in the Linux perf section. This flame graph is partially-useful, as I can see system and v8 library symbols.

Flame graphs are a CPU profiling visualization technique that helps to spot at glance the most frequently used function, and most importantly the time they need to run. On y-axis will be the stack trace height, on the x-axis the CPU time for the function to finish. Big and wide flames = Excessive CPU usage.

The most popular tool is flame graphs. Flame graphs were invented by Brendan Gregg in 2011. While it was possible to create flame graphs for profiled Erlang code many years ago, what is new is that these flame graphs can now be created with accurate call stack reporting without a noticeable slowdown of the Erlang program.

Flame graphs can be created in three steps: Capture stacks. Fold stacks. flamegraph.pl. 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. Linux perf_events.

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.
