Monitor Docker Services Using Grafana, Prometheus & cAdvisor — Without Touching the CLI

  If you're running Docker containers on a server, monitoring their performance using command-line tools can be time-consuming and difficult to visualize. In this guide, I’ll show you how to monitor your Docker services using Grafana, Prometheus, and cAdvisor—all through a web interface, without relying on CLI tools after setup.
