Types

type Packet

type Packet struct {
	// Rtt is the round-trip time it took to ping.
	Rtt time.Duration

	// IPAddr is the address of the host being pinged.
	IPAddr *net.IPAddr

	// Addr is the string address of the host being pinged.
	Addr string

	// NBytes is the number of bytes in the message.
	Nbytes int

	// Seq is the ICMP sequence number.
	Seq int

	// TTL is the Time To Live on the packet.
	TTL int
}

Packet represents a received and processed ICMP echo packet.

type Pinger

type Pinger struct {
	// Interval is the wait time between each packet send. Default is 1s.
	Interval time.Duration

	// Timeout specifies a timeout before ping exits, regardless of how many
	// packets have been received.
	Timeout time.Duration

	// Count tells pinger to stop after sending (and receiving) Count echo
	// packets. If this option is not specified, pinger will operate until
	// interrupted.
	Count int

	// Debug runs in debug mode
	Debug bool

	// Number of packets sent
	PacketsSent int

	// Number of packets received
	PacketsRecv int

	// OnRecv is called when Pinger receives and processes a packet
	OnRecv func(*Packet)

	// OnFinish is called when Pinger exits
	OnFinish func(*Statistics)

	// Size of packet being sent
	Size int

	// Tracker: Used to uniquely identify packet when non-priviledged
	Tracker int64

	// Source is the source IP address
	Source string
	// contains filtered or unexported fields
}

Pinger represents ICMP packet sender/receiver

func NewPinger

func NewPinger(addr string) (*Pinger, error)

NewPinger returns a new Pinger struct pointer

func (*Pinger) Addr

func (p *Pinger) Addr() string

Addr returns the string ip address of the target host.

func (*Pinger) IPAddr

func (p *Pinger) IPAddr() *net.IPAddr

IPAddr returns the ip address of the target host.

func (*Pinger) Privileged

func (p *Pinger) Privileged() bool

Privileged returns whether pinger is running in privileged mode.

func (*Pinger) Run

func (p *Pinger) Run() error

Run runs the pinger. This is a blocking function that will exit when it's done. If Count or Interval are not specified, it will run continuously until it is interrupted.

func (*Pinger) SetAddr

func (p *Pinger) SetAddr(addr string) error

SetAddr resolves and sets the ip address of the target host, addr can be a DNS name like "www.google.com" or IP like "127.0.0.1".

func (*Pinger) SetIPAddr

func (p *Pinger) SetIPAddr(ipaddr *net.IPAddr)

SetIPAddr sets the ip address of the target host.

func (*Pinger) SetPrivileged

func (p *Pinger) SetPrivileged(privileged bool)

SetPrivileged sets the type of ping pinger will send. false means pinger will send an "unprivileged" UDP ping. true means pinger will send a "privileged" raw ICMP ping. NOTE: setting to true requires that it be run with super-user privileges.

func (*Pinger) Statistics

func (p *Pinger) Statistics() *Statistics

Statistics returns the statistics of the pinger. This can be run while the pinger is running or after it is finished. OnFinish calls this function to get it's finished statistics.

func (*Pinger) Stop

func (p *Pinger) Stop()

Stop falan filan

type Statistics

type Statistics struct {
	// PacketsRecv is the number of packets received.
	PacketsRecv int

	// PacketsSent is the number of packets sent.
	PacketsSent int

	// PacketLoss is the percentage of packets lost.
	PacketLoss float64

	// IPAddr is the address of the host being pinged.
	IPAddr *net.IPAddr

	// Addr is the string address of the host being pinged.
	Addr string

	// Rtts is all of the round-trip times sent via this pinger.
	Rtts []time.Duration

	// MinRtt is the minimum round-trip time sent via this pinger.
	MinRtt time.Duration

	// MaxRtt is the maximum round-trip time sent via this pinger.
	MaxRtt time.Duration

	// AvgRtt is the average round-trip time sent via this pinger.
	AvgRtt time.Duration

	// StdDevRtt is the standard deviation of the round-trip times sent via
	// this pinger.
	StdDevRtt time.Duration
}

Statistics represent the stats of a currently running or finished pinger operation.
