Monitoring Docker

By: Russ McKendrick

Overview of this book

This book will show you how monitoring containers and keeping a keen eye on the working of applications helps improve the overall performance of the applications that run on Docker. With the increased adoption of Docker containers, the need to monitor which containers are running, what resources they are consuming, and how these factors affect the overall performance of the system has become the need of the moment. This book covers monitoring containers using Docker's native monitoring functions, various plugins, as well as third-party tools that help in monitoring. Well start with how to obtain detailed stats for active containers, resources consumed, and container behavior. We also show you how to use these stats to improve the overall performance of the system. Next, you will learn how to use SysDig to both view your containers performance metrics in real time and record sessions to query later. By the end of this book, you will have a complete knowledge of how to implement monitoring for your containerized applications and make the most of the metrics you are collecting

Datadog is a full monitoring platform; it supports various servers, platforms, and applications. Wikipedia describes the service as:

"Datadog is a SaaS-based monitoring and analytics platform for IT infrastructure, operations and development teams. It brings together data from servers, databases, applications, tools and services to present a unified view of the applications that run at scale in the cloud."

It uses an agent that is installed on your host machine; this agent sends metrics back to the Datadog service periodically. It also support multiple cloud platforms, such as Amazon Web Services, Microsoft Azure, and OpenStack to name a few.

The aim is to bring all of your servers, applications, and host provider metrics into a single pane of glass; from here, you can create custom dashboards and alerts so that you can be notified of any problem at any level within your infrastructure.
