Best Docker Container Monitoring Tools - Free and open source

Step-by-Step Tutorial: Best Docker Container Monitoring Tools

1. Using Docker Stats Command:

• The docker stats command is a built-in solution in Docker that provides quick and easy statistics and performance information about your Docker containers.
• To use it, open your terminal and issue the docker stats command.
• This command will display information like container ID, name, CPU percentage, memory usage, net IO, block IO, and PIDs for running containers.
• You can explore additional options like --all, --no-stream, and --no-trunc for more specific information retrieval.

2. Using Glances:

• Glances is a command-line tool with a web interface that offers more detailed information than docker stats.
• Deploy Glances as a Docker container on your Docker host.
• Access the Glances dashboard to view information about your Docker container host, CPU, memory, network, disk IO, and detailed container information.
• Glances provides a single dashboard for all your monitoring needs, allowing you to easily navigate and troubleshoot.

3. Using Portainer:

• Portainer is a versatile tool for Docker container monitoring, configuration, and administration.
• Deploy Portainer as a Docker container on your host to access its dashboard.
• Explore the Portainer dashboard to get insights into stacks, images, networks, containers, volumes, and GPUs.
• Utilize quick actions within Portainer to monitor, troubleshoot, and interact with your containers effectively.

4. Using Zabbix:

• Zabbix is a powerful open-source monitoring solution that extends beyond Docker environments to Kubernetes, Linux hosts, Windows hosts, networks, applications, and more.
• Add your Docker container host to Zabbix to access detailed graphs showing container status, network traffic, historic data, and host performance metrics.
• Use Zabbix to monitor both individual containers and the overall Docker container host for comprehensive insights and troubleshooting.

5. Using Check MK:

• Check MK is a user-friendly monitoring solution for Docker container hosts and individual containers.
• Add your Docker container host to Check MK to start streaming monitoring information.
• Check MK provides performance metrics in a condensed view, allowing you to easily identify key performance indicators and troubleshoot any issues.
• Drill down into individual container metrics to analyze CPU utilization, disk IO, memory usage, and more for detailed monitoring.

6. Exploring Additional Monitoring Solutions:

• Consider exploring other Docker monitoring solutions mentioned in the video or recommended by others.
• Experiment with different tools in your lab environment to find the best fit for your monitoring needs.
• Share your experiences and recommendations in the comments section of the video to contribute to the community's knowledge on Docker monitoring solutions.

By following these steps, you can effectively monitor your Docker containers using a variety of free and open-source tools mentioned in the video "Best Docker Container Monitoring Tools - Free and open source" by VirtualizationHowto.
