Datadog Cloud Monitoring Quick Start Guide

By: Thomas Kurian Theakanath

Overview of this book

Datadog is an essential cloud monitoring and operational analytics tool which enables the monitoring of servers, virtual machines, containers, databases, third-party tools, and application services. IT and DevOps teams can easily leverage Datadog to monitor infrastructure and cloud services, and this book will show you how. The book starts by describing basic monitoring concepts and types of monitoring that are rolled out in a large-scale IT production engineering environment. Moving on, the book covers how standard monitoring features are implemented on the Datadog platform and how they can be rolled out in a real-world production environment. As you advance, you'll discover how Datadog is integrated with popular software components that are used to build cloud platforms. The book also provides details on how to use monitoring standards such as Java Management Extensions (JMX) and StatsD to extend the Datadog platform. Finally, you'll get to grips with monitoring fundamentals, learn how monitoring can be rolled out using Datadog proactively, and find out how to extend and customize the Datadog platform. By the end of this Datadog book, you will have gained the skills needed to monitor your cloud infrastructure and the software applications running on it using Datadog.

Once an agent is up and running on a host, the agent starts reporting into the Datadog backend in the cloud. The host will get added to the infrastructure lists once communication between the agent running on it and the backend is successfully established.

The infrastructure lists are available underneath the Infrastructure main menu. The most important ones are Host Map and Infrastructure List:

Each block in a Host Map menu represents a host where an agent is running. In the following screenshot, the green color indicates that the agent is active and able to communicate with the backend. The orange color indicates some trouble with communication; however, it also indicates that, at some point in the past, the related agent was able to connect to the backend:
