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.

Viewing logs using Live Tail

Datadog's Live Tail feature makes the logs available on the logs dashboards as soon as they are available in the backend. It's inspired by the Unix shell command tail, which continuously puts out any additions to a log file that it tracks. The advantage with Live Tail is that updates to a set of similar log files from multiple sources can be tracked on one dashboard.

The Live Tail option is available on the Containers dashboard as in the following screenshot:

Log Explorer also has a Live Tail option available as shown in the following screenshot:

In this section, you have learned how the Live Tail option can be useful in terms of looking at the logs and reporting on them on a regular basis. In the next section, you will learn how to search a vast number of logs that would be collected...
