go-mtr
A go wrapper on the mtr process. This package uses mtr --raw and
parses the output. The results are slightly different than running
mtr --report directly because mtr itself keeps a running total
of the mean/standard deviation/interarrival jitter/etc. This package
calculates these values over the entire package sequence.
mtr is required to use this package.
Documentation can be found on godoc.

Types ¶
type Host ¶
type Host struct {
IP net.IP `json:"ip"`
Name string `json:"hostname"`
Hop int `json:"hop-number"`
PacketMicrosecs []int `json:"packet-times"`
Sent int `json:"sent"`
Received int `json:"received"`
Dropped int `json:"dropped"`
LostPercent float64 `json:"lost-percent"`
// All packet units are in microseconds
Mean float64 `json:"mean"`
Best int `json:"best"`
Worst int `json:"worst"`
StandardDev float64 `json:"standard-dev"`
MeanJitter float64 `json:"mean-jitter"`
WorstJitter int `json:"worst-jitter"`
InterarrivalJitter int `json:"interarrival-jitter"` // calculated with rfc3550 A.8 shortcut
}
type MTR ¶
type MTR struct {
Done chan struct{}
OutputRaw []byte
Error error
PacketsSent int
Hosts []*Host `json:"hosts"`
}
func New ¶
New runs mtr --raw -c reportCycles hostname args... Thus, you can add more arguments to the default required hostname and report cycles. The MTR call is signified as done when the MTR.Done chan closes. First wait for this, then check the MTR.Error field before looking at the output. Other than that, the fields and json tags document what everything means.
