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

Chapter 3. Advanced Container Resource Analysis

In the last chapter, we looked at how you can use the API built into Docker to gain an insight to what resources your containers are running. Now, we are to see how we can take it to the next level by using cAdvisor from Google. In this chapter, you will cover the following topics:

  • How to install cAdvisor and start collecting metrics

  • Learn all about the web interface and real-time monitoring

  • What your options are for shipping metrics to a remote Prometheus database for long-term storage and trend analysis
