Monitoring containerized applications is essential for ensuring optimal performance, diagnosing issues promptly, and maintaining overall system health. Monitoring containerized applications is essential for ensuring optimal performance, diagnosing issues promptly, and maintaining overall system health.
In a dynamic environment where containers can be spun up or down based on demand, having a flexible and responsive monitoring solution becomes even more critical. This article delves into how I utilize the Netdata REST API to generate real-time, visually appealing graphs and an interactive dashboard for each container dynamically. By integrating technologies like Node.js, Express.js, Chart.js, Docker, and Ib sockets, I create a seamless monitoring experience that provides deep insights into container performance metrics.

As containerization becomes the backbone of modern application deployment, monitoring solutions need to adapt to the ephemeral nature of containers. Traditional monitoring tools may not provide the granularity or real-time feedback necessary for containerized environments. Netdata, with its poIrful real-time monitoring capabilities and RESTful API, offers a robust solution for collecting and accessing performance metrics. By leveraging the Netdata REST API, I can fetch detailed metrics about CPU usage, memory consumption, network traffic, disk I/O, and running processes within each container.

Our goal is to create an interactive dashboard that not only displays these metrics in real-time but also provides users with the ability to interact with the data, such as filtering processes or adjusting timeframes. To achieve this, I build a backend server that interfaces with the Netdata API, processes the data, and serves it to the frontend where it's rendered using Chart.js and other Ib technologies.
