fakeadog is a go library for parsing datadog events

Fakeadog

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
