Ep2 Installing Prometheus + Node Exporter | Give Your System Eyes | DevOps Monitoring Explained
In the last episode, our production app went completely dark — no metrics, no alerts, no clue what was happening.
Today, we’re changing that. In this hands-on episode, we install Prometheus + Node Exporter and give our system “eyes” for the first time. 👀
You’ll learn how Prometheus scrapes metrics, what Node Exporter does under the hood, and how data collection becomes the foundation of real-time monitoring.
💡 What you’ll learn:
– How Prometheus collects and stores system metrics
– Understanding Node Exporter and the /metrics endpoint
– Using Docker Compose to spin up Prometheus + Node Exporter
– Visualizing your first metrics in Prometheus UI
– Concepts: scrape interval, jobs, labels, and targets
🔥 Next Episode → Visualize your metrics with Grafana Dashboards and see your system come alive.
