In today’s FusionPact Daily DevOps Session, we dive deep into “Continuous Monitoring using Prometheus + Grafana with Docker” — with real-world industry examples from production systems. This session explains why monitoring is essential for modern DevOps teams and how it solves critical developer headaches such as blind deployments, slow issue detection, CPU spikes, memory leaks, and unpredictable production failures. Based on the complete session document shared in this training. ✔ Why developers struggle without monitoring: Blind deployments Slow issue detection Firefighting mode instead of prevention Unknown performance bottlenecks ✔ Complete solution using: Prometheus Grafana Docker ✔ What metrics real companies monitor: Container Metrics → CPU, Memory, Network I/O, Disk throughput System Metrics → Load average, uptime, process count Application Metrics → Latency, throughput, error rate ✔ Architecture explained with exporterd like Node Exporter, cAdvisor, etc. 🏭 Real-Time Industrial Examples [Included in This Video] 1️⃣ E-commerce Industry – CPU Spike During Flash Sale A CPU alert fires. Grafana shows one checkout container hitting 95% CPU. DevOps identifies a slow SQL query → fixes it within minutes → avoids checkout failure. 2️⃣ SaaS Company – Memory Leak in Microservices Grafana dashboards show memory rising slowly for a recommendation service. Alert triggers → engineer restarts and patches the service before customers notice. 3️⃣ FinTech – Cascading Failures in Payment Pipeline A downstream API slows down → latency increases → multiple services fail. Grafana + Prometheus help trace dependency chain → root cause fixed under 10 minutes. 4️⃣ Deployment Monitoring in Real Teams Immediately after a deployment, dashboards show sudden spike in error rates. Teams roll back changes instantly instead of waiting for customer complaints. ⚙️ What This Video Demonstrates (Hands-On) How Prometheus scrapes metrics every 15 seconds How Grafana visualizes real-time dashboards How alerts notify teams How DevOps engineers use historical trends to identify root cause How continuous monitoring reduces downtime and increases reliability 🚀 Who Should Watch This Training? DevOps Engineers SRE & Platform Engineers Cloud Engineers Backend Developers Anyone working with Docker, microservices, or production systems 📌 Key Takeaways Monitoring → transforms firefighting into proactive prevention Prometheus + Grafana → 100% open-source, quick to deploy, industry standard Real-time visibility → reduces debugging time from hours to minutes Helps prevent outages, production incidents, and customer impact 🔗 More From FusionPact We upload DevOps training videos daily.
