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

Summary


As discussed in this chapter, Docker is a fast moving technology. While this book has been in production, there have been three major versions released from 1.7 to 1.9; with each release Docker has become more stable and more powerful.

In this chapter, we have looked at different ways to implement the technologies that have been discussed in the previous chapters of this book. By now, you should have an idea of which approach is appropriate to monitor your containers and host machines, for both your application and for the way the application has been deployed using Docker.

No matter which approach you chose to take, it is important that you stay up-to-date with Docker's development and also the new monitoring technologies as they emerge, the following links are good starting points to keep yourself informed:
