func Fqdn ¶

func Fqdn(hostname string) string

Fqdn returns the FQDN for the host if any (this uses a DNS forward and reverse round trip).

func IsUDSAvailable ¶

func IsUDSAvailable(path string) bool

IsUDSAvailable checks if the given path refers to an existing Unix domain socket that the current process can write to. This is intended for verifying that a DogStatsD UDS datagram socket is ready to receive data.

It checks three things:

1. The path exists on disk.
2. The file is a socket.
3. The current process has write permission.
