In the tenth installment of the Nginx Advanced series, we dive into observability—a critical aspect of modern infrastructure management. This episode focuses on leveraging Prometheus and Grafana to monitor Nginx performance and health.
The foundation of observability rests on three pillars: logs, metrics, and traces. The video demonstrates how to expose Nginx metrics using the stub_status module, then scrape those metrics into Prometheus, and finally visualize them with a pre-built Grafana dashboard (ID 12708). The tutorial also covers OpenTelemetry-based distributed tracing and production deployment patterns.
By the end, you'll have a fully functional monitoring stack that provides real-time insights into request rates, connections, and error rates—empowering you to proactively optimize your Nginx infrastructure.
