Prometheus Configuration

Solid Prometheus setup guide that covers the essentials without getting lost in the weeds. Handles scrape configs for static targets, Kubernetes service discovery, and file-based discovery, plus generates useful recording rules for request rates and error percentages. The alert rules are practical, covering service downtime, error rates, and resource utilization with sensible thresholds. Docker Compose and Helm charts are included for quick deployment. What I like is the clear architecture diagram and real-world relabeling configs that actually work in production environments.
