# go-iperf
A Go based wrapper around iperf3
## Basic Usage
basic client setup
```go
func main() {
c := iperf.NewClient("192.168.0.10")
c.SetJSON(true)
c.SetIncludeServer(true)
c.SetStreams(4)
c.SetTimeSec(30)
c.SetInterval(1)
err := c.Start()
if err != nil {
fmt.Printf("failed to start client: %v\n", err)
os.Exit(-1)
}
<- c.Done
fmt.Println(c.Report().String())
}
```
basic server setup
```go
func main() {
s := iperf.NewServer()
err := s.Start()
if err != nil {
fmt.Printf("failed to start server: %v\n", err)
os.Exit(-1)
}
for s.Running() {
time.Sleep(100 * time.Millisecond)
}
fmt.Println("server finished")
}
```
client with live results printing
```go
func main() {
c := iperf.NewClient("192.168.0.10")
c.SetJSON(true)
c.SetIncludeServer(true)
c.SetStreams(4)
c.SetTimeSec(30)
c.SetInterval(1)
liveReports := c.SetModeLive()
go func() {
for report := range liveReports {
fmt.Println(report.String())
}
}
err := c.Start()
if err != nil {
fmt.Printf("failed to start client: %v\n", err)
os.Exit(-1)
}
<- c.Done
fmt.Println(c.Report().String())
}
```
building binary data package with iperf binaries
```
go-bindata -pkg iperf -prefix "embedded/" embedded/
```
go-bindata -pkg iperf -prefix "embedded/" embedded/```
