For example, to generate a kernel CPU flame graph using DTrace, by sampling kernel stacks at 197 Hertz for 60 seconds:The flame graph is able to visualize all the history stack trace. Flamegraph can contain much more info than a traditional GDB crash stacktrace because it remembers all history function calls. So my question is : can flamegraph satisfy what I am looking for? I heard that flamegraph do samplings, so I am afraid it will lose function calls.

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.
