Docker Container Monitoring: Protect Your Investment

Has your boss asked you about Docker containers yet? No? Well, I’ll wait. He’s probably on the way to your desk or office right now.

Why? Because your company is probably already using containers, whether it’s for testing or for production, and Docker is the most common container platform out there. The companies using Docker containers are using more every year. Docker containers offer flexibility, efficiency, and work well with DevOps and agile methodologies.

If you’ve begun using containers, you’re likely wondering how best to protect your investment. Whether deployed on-premise or in the cloud, you need to know how your containers are performing, especially since containers are becoming the backbone of mission-critical services.

Effective monitoring will allow your system administrators to react to and resolve issues quickly. To set up the right monitoring, you’ll need to know what to monitor and what tools are available to help you. First, we’ll look at the challenges of monitoring Docker containers.

The Unique Challenges of Monitoring Docker Containers

Containers help you to use computing resources efficiently. They’re easy to deploy and are perfect for holding microservices. This separation of small pieces, however, leads to increased complexity.

Your users see one application. To them, microservices are like the ants behind the ant hill. You see the results of the work, but not the tiny little soldiers working together to build it. Your application is not one piece, but multiple separate services that link together to perform the necessary functions.

Now each one of these little services and the containers they occupy needs to be monitored. Monitoring such complex architectures is a challenge. But it can be done effectively.
