Types

type Probe

type Probe struct {
	FQDN         string `json:"fqdn"`         // IP or Hostname
	RecordType   string `json:"recordtype" `  // Record Type to Lookup
	StrictAnswer bool   `json:"strictanswer"` // Attend uniquement la valeur
	NameServer   string `json:"nameserver" `  // Send Request to a specified Nameserver
}

Probe struct. Json and yaml descriptor are used for json output

func (*Probe) GenerateTStepName

func (*Probe) Initialize

func (p *Probe) Initialize(step probe.StepProbe) error

Initialize Probe struct data

func (*Probe) Run

func (p *Probe) Run(timeout time.Duration) (probeReturn []probe.ProbeReturn)

Start the probe request

type ProbeAnswer

type ProbeAnswer struct {
	Answer       []string        `json:"answer"`
	TTL          int             `json:"ttl"`
	ResponseTime float64         `json:"responsetime"` // Reference Time Unit = Second
