Flame graph

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.
