Inspired by Lee Hambley's Ruby script.
Fakeadog can be used as an aid for testing emitting DataDog metrics locally without having to install a full-blown DataDog client.
Usage: fakeadog -host $HOST -port $PORT
To install: go get -u github.com/johnstcn/fakeadog
The program leverages the library fakeadog/parser for parsing DataDog events from raw UDP packets.
Example usage:
import "github.com/johnstcn/fakeadog/parser"
func main() {
parser := parser.NewDataDogParser()
payload := []byte{"myapp.frobble.count:1|c|#app:myapp,hostname:myhost"}
metric, err := parser.Parse(payload)
fmt.Printf("%s\n", metric) # C myap.frobble.count 1 [app:myapp hostname:myhost]
}
Example docker usage:
$ docker run --rm --net=host johnstcn/fakeadog
You can also pull the image from Docker Hub
$ docker pull johnstcn/fakeadog:latest
