DataDog is a monitoring service for cloud-scale applications, in the following guide we’ll see how to create a docker container with the DataDog agent and how to use it to publish custom metrics.

In this guide I will show you how to use gRPC to write a simple client (in C++) and server (in Go) for your service.

For this tutorial we will use the code available in the following Github project: pasdam/grpcExample.

For the client, in this article I’ll show how to write a command line one, but in the repository there is also a GUI client written with the Qt framework.
