How I Built a Centralized Monitoring System for 600–700 Servers — Using Open Source Tools
Built a centralized monitoring and logging system using **Grafana, Prometheus, Loki, Promtail, and cAdvisor** — all containerized with Docker and hosted on a single AWS EC2 instance. The stack monitors **600–700+ client servers** across multiple clients with unified dashboards, real-time alerting, and centralized log search. Label-based isolation ensures each client's data stays organized, with dynamic Grafana templates enabling instant filtering by client, environment, and service. The result: faster incident detection, reduced MTTR, and a cost-effective open-source alternative to heavy tools like the ELK stack.
