Send data to Datadog using Go

Question

i'm collect data using Go and want to visualize it, i chose Datadog, but didn't find examples or live projects where Go used for sending metrics to Datadog. But in offical site says that Go is supported.

Answer 1

First step is to install the DataDog agent on the server in which you are running your application:

https://docs.datadoghq.com/agent/

You then need to enable the DogStatsD service in the DataDog agent:

https://docs.datadoghq.com/developers/dogstatsd/

After that, you can send metrics to the statsd agent using any Go library that connects to statsd.

For example:

https://github.com/DataDog/datadog-go

https://github.com/go-kit/kit/tree/master/metrics/statsd

Here's an example program sending some counts using the first library:

import (
    "github.com/DataDog/datadog-go/statsd"
    "log"
)

func main() {
    // Create the client
    c, err := statsd.New("127.0.0.1:8125")
    if err != nil {
        log.Fatal(err)
    }
    // Prefix every metric with the app name
    c.Namespace = "myapp."
    // Count two events
    err = c.Count("my_counter", 2, nil, 1)
    if err != nil {
        log.Fatal(err)
    }
    // Close the client
    err = c.Close()
    if err != nil {
        log.Fatal(err)
    }
}
