Real-Time CPU Monitoring with Prometheus & Grafana Tutorial
Learn how to monitor your CPU in real-time using Prometheus and Grafana on Ubuntu with Node Exporter. In this step-by-step Prometheus and Grafana monitoring tutorial, you’ll see how to track CPU usage, visualize metrics on a Grafana dashboard, and understand the key concepts of server monitoring. Perfect for DevOps beginners, this guide covers Prometheus monitoring with Grafana, setting up Node Exporter, and creating dashboards that instantly show CPU spikes. You’ll also learn how real-time server monitoring works, how to use Prometheus queries, and why this setup is widely used in production environments for Linux server monitoring.
By the end of this tutorial, you’ll be able to set up your own Grafana and Prometheus monitoring project, monitor Ubuntu servers, and understand DevOps monitoring tools for tracking CPU, RAM, and system load efficiently.
