Capture stacks\n2. Fold stacks\n3. flamegraph.pl\n\n1\\. Capture stacks\n=================\nStack samples can be captured using Linux perf\\_events, FreeBSD pmcstat (hwpmc), DTrace, SystemTap, and many other profilers. See the stackcollapse-\\* converters.\n\n### Linux perf\\_events\n\nUsing Linux perf\\_events (aka \"perf\") to capture 60 seconds of 99 Hertz stack samples, both user- and kernel-level stacks, all processes:\n\n```\n# perf record -F 99 -a -g -- sleep 60\n# perf script \u003e out.perf\n```\n\nNow only capturing PID 181:\n\n```\n# perf record -F 99 -p 181 -g -- sleep 60\n# perf script \u003e out.perf\n```\n\n### DTrace\n\nUsing DTrace to capture 6",
