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

Zabbix


First things first, what is Zabbix and why use it?

I have personally been using it since version 1.2; the Zabbix site describes it as follows:

"With Zabbix, it is possible to gather virtually limitless types of data from the network. High-performance real-time monitoring means that tens of thousands of servers, virtual machines, and network devices can be monitored simultaneously. Along with storing the data, visualization features are available (overviews, maps, graphs, screens, and so on), as well as very flexible ways of analyzing the data for the purpose of alerting.

Zabbix offers great performance for data gathering and can be scaled to very large environments. Distributed monitoring options are available with the use of Zabbix proxies. Zabbix comes with a web-based interface, secure user authentication, and a flexible user permission schema. Polling and trapping is supported, with native high-performance agents gathering data from virtually any popular operating system; agent-less...
