I have a dummy GO plugin, using that, i want send data to telegraf. But, i’m not able to find any way to send data from the plugin to telegraf. this external Go plugin looks like below…
package main
import (
"fmt"
"time"
)
type greeting string
type n int
func (g greeting) Greet() {
for i := 0; i < 10; i++ {
timer1 := time.NewTimer(2 * time.Second)
<-timer1.C
fmt.Println("value ", i)
sum := 0
sum += i * 100
fmt.Println(sum)
}
}
// exported
var Greeter greeting
And the main file looks like
import (
"fmt"
"os"
"plugin"
)
type Greeter interface {
Greet()
}
func main() {
var mod string
mod = "./eng/eng.so"
// load module
// 1. open the so file to load the symbols
plug, err := plugin.Open(mod)
if err != nil {
fmt.Println(err)
os.Exit(1)
}
// 2. look up a symbol (an exported function or variable)
// in this case, variable Greeter
symGreeter, err := plug.Lookup("Greeter")
if err != nil {
fmt.Println(err)
os.Exit(1)
}
// 3. Assert that loaded symbol is of a desired type
// in this case interface type Greeter (defined above)
var greeter Greeter
greeter, ok := symGreeter.(Greeter)
if !ok {
fmt.Println("unexpected type from module symbol")
os.Exit(1)
}
// 4. use the module
greeter.Greet()
}
Can anyone help me find a way or a direction on how to make interaction between GO plugin and telegraf work. Any heads up is appreciated.
