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.

Monitoring networks using SNMP

Simple Network Management Protocol (SNMP) is a protocol for managing equipment within a network. It has been used to track the devices in networks and their performance, and vendors have adopted it as the standard for publishing related data. Even though in a public cloud environment the requirement for networking monitoring is minimal to nil, in a large-scale operational environment, setting up a colocation to connect to a customer or managing some physical network equipment internally is always possible. Plugging in that equipment to the existing Datadog platform could be handy, instead of rolling out a different monitoring solution for that.

On SNMP-enabled devices, the agent collects the performance metrics from the devices and stores them in a Management Information Base (MIB) for network monitoring tools to consume. snmpwalk is a popular command-line tool that is used to scan devices for such data. Datadog integrates with SNMP and an agent can...
