Here is my code:
cmd := exec.Command("go", "tool", "pprof", "-dot", "-lines", "http://google.com")
out, err := cmd.Output()
if err != nil {
panic(err)
}
println(string(out))
When I run the exact same command in my console, I see:
$ go tool pprof -dot -lines http://google.com
Fetching profile from http://google.com/profilez
Please wait... (30s)
server response: 404 Not Found
However, my go program does not register that this is an error. Oddly, the variable out prints as an empty string and err is nil. What is going on?
To clarify, I am profiling http://google.com to purposefully create an error. I would normally profile a real Go application.
