Welcome to Episode 3 of the Monitoring & Alerting in Real Life series! Now that Prometheus and Alertmanager are up and running, it’s time to give your data a face — Grafana. In this episode, you’ll learn how to build beautiful, real-time dashboards that visualize system health, app metrics, and alert activity all in one place. This is where monitoring transforms into observability. 🎯 What You’ll Learn: Connect Grafana to Prometheus Build dashboards for CPU, Memory, Uptime, and App Errors Add color thresholds for visual impact (green/yellow/red) Use Stat, Gauge, and Time-Series visualizations effectively Save dashboards with volumes so they persist after restart Make your panels production-ready with labels and units 💡 Hands-On Setup: Prometheus + Grafana + Node Exporter in Docker Compose Real metrics from your Flask app Visual alert panels from Alertmanager integration 📊 By the End: You’ll have a live Grafana dashboard showing your app’s health in real time — the same setup used in real companies for monitoring and incident response. 👉 Watch the full series playlist: [link to playlist] 👉 Get all reproducible labs + source code: https://learnwithdevopsengineer.beehiiv.com/subscribe Github repo - https://github.com/learnwithdevopsengineer3682/docker-home-lab-series 📺 Watch Next: DevOps HomeLab Series - https://youtu.be/a2XtV0piToU DevOps in Production: Real-World Simulations - https://www.youtube.com/playlist?list=PLC3q1iUHNvtV7dxVrkJngsapxabQDEEmw DevOps Home Lab Bootcamp – Build Real Skills at Home - https://www.youtube.com/playlist?list=PLC3q1iUHNvtVHt9QXnWSD3anLZY63PTkt DevOps in Production: Real-World Simulations - https://www.youtube.com/playlist?list=PLC3q1iUHNvtV7dxVrkJngsapxabQDEEmw DevOps in Action: Real Incidents, Debugging & Automation - https://www.youtube.com/playlist?list=PLC3q1iUHNvtVNTF5W_uvFUFQBvwUqxMjv Github Repo - https://github.com/learnwithdevopsengineer3682/devops-homelab-series/
