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

In this chapter, we learned how to take the viewing real-time statistics of our containers off the command line and into the web browser. We explored some different methods to install Google's cAdvisor application and also how to use its web interface to keep an eye on our running containers. We also learned how to capture metrics from cAdvisor and store them using Prometheus, a modern time series database.

The two main technologies we have covered in this chapter have only been publically available for less than twelve months. In the next chapter, we will look at using a monitoring tool that has been in a SysAdmins toolbox for over 10 years—Zabbix.
