pprof unrecognized profile format

go tool pprof -http=:8080 http://10.179.90.133:9981/debug/pprof/trace?seconds=60
Fetching profile over HTTP from http://10.179.90.133:9981/debug/pprof/trace?seconds=60
^[[A http://10.179.90.133:9981/debug/pprof/trace?seconds=60: parsing profile: unrecognized profile format
failed to fetch any source profiles

原因
trace的格式和profile的格式不一样，因此用pprof没法解析
应该用go tool trace

go tool trace -http=:8080 http://10.179.90.133:9981/debug/pprof/trace?seconds=60

go tool pprof http://localhost:6060/debug/pprof/heap这种方式出现了错误parsing profile: unrecognized profile format

少了一些东西，应该是这样 go tool pprof http://127.0.0.1:8601/debug/pprof/heap?debug=1，或者使用浏览器直接访问 http://127.0.0.1:8601/debug/pprof/ ，最后的斜杠不要忘了
