A comment on Profiling Go Applications with Flamegraphs.
- Linux perf can profile unmodified Go programs. This is handy when your application doesn't expose the /debug/pprof endpoint. (http://brendangregg.com/FlameGraphs/cpuflamegraphs.html#perf has detailed instructions)
- Recent versions of https://github.com/google/pprof include a flamegraph viewer in the web UI. This is handy when you want a line-level flamegraph instead of a function-level flamegraph.
