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.

In an environment where more elastic and immutable infrastructure is preferred, such manual steps are either not preferred or discouraged. In such situations, the option of viewing the processes running on the hosts is very useful. Also, having the processes listed in one place makes comparing the runtime environments of two or more hosts easier.

To get to the Processes dashboard, navigate to Infrastructure | Processes on the Datadog dashboard. You will see an interface similar to the one shown in the following screenshot:

This dashboard is similar to what we saw regarding the Containers dashboard in the previous section. On the left pane, there are search and filter options that you can use to locate the processes that...
