https://colobu.com/2017/03/02/a-short-survey-of-golang-pprof/ pprof 用法： 安装 如下工具，然后执行 最后的 go tool pprof xxx 命令（不带 web 进入命令行，可以自由生成各种格式：pdf、png、svg等等）。

$ brew install gperftools $ brew install graphviz

go tool pprof -web http://10.75.25.126:9091/debug/pprof/profile

火焰图 (Flame Graph) https://colobu.com/2017/03/02/a-short-survey-of-golang-pprof/ go-torch 用法： 1.安装 2.在 brendangregg/FlameGraph 目录下执行 go-torch，或者加 PATH

$ go get github.com/uber/go-torch $ git clone git@github.com:brendangregg/FlameGraph.git $ export PATH-$PATH:/path/to/FlameGraph

go-torch --file "torch.svg" --url http://localhost:6060
