  Introduction Monitoring is the backbone of modern DevOps and SRE (Site Reliability Engineering) practices. Without proper monitoring, even the most robust infrastructure can fail silently. This is where Prometheus and Grafana come in — one collects and processes metrics, the other visualizes them beautifully. Together, they form one of the most powerful monitoring stacks in the DevOps ecosystem. In this complete guide, we’ll cover everything about Prometheus and Grafana, from basic setup to advanced scaling , and how you can use them to master infrastructure monitoring like a pro. Getting Started with Prometheus Prometheus is an open-source monitoring and alerting toolkit designed for reliability and scalability. Originally developed at SoundCloud, it’s now a CNCF (Cloud Native Computing Foundation) project. Core Features of Prometheus Multi-dimensional data model Powerful query language (PromQL) Pull-based metric collection Integrated alerting with Alertm...
