[weichangdong]

gops memstats 27281 couldn't get port by PID: dial tcp 127.0.0.1:0: connect: can't assign requested address when i use addr,long time no response. i use go version go1.10 darwin/amd64. i remember it works before,perhaps i updated the go version.

1、golang version 2、quote "github.com/google/gops/agent" in your code; 3、add code in you main func, such as: if err := agent.Listen(agent.Options{}); err != nil { log.Fatal(err) } 4、go build your code 5、run your binary program 6、gops option according to gops doc

to use gops, you MUST set env of GOPS_CONFIG_DIR, otherwise, it use $HOME/.config for linux system, in case the dir does not exist, gops will mkdir, but for which you might have no permission to mkdir

func PIDFile(pid int) (string, error) { gopsdir, err := ConfigDir() if err != nil { return "", err } return fmt.Sprintf("%s/%d", gopsdir, pid), nil }
