Functions

func CurrentIP

func CurrentIP() (ip string)

CurrentIP returns the device's current public IP address.

func IfaceHash

func IfaceHash() string

IfaceHash generates a unique device identifier based on the MAC addresses of hardware interfaces.

I'm concerned that this isn't a good way to generate device identifiers. Alternatives: use a file to store a generated UUID.

type Metrics struct {
	CPUPercent float64 `json:"cpuUsage"`
