One of the best means of monitoring your containers is an open source tool, found on Github, called ctop. With this app, you can get a quick overview of your containers, their names, IDs, and how much CPU, Memory, and Network Rx/Tx data. Ctop even allows you to filter what you’re viewing, and gives you an expanded view of a selected container. Although it may not offer a massive amount of features, it does the job and does it well. The tool is easy to install, and even easier to use.
