Monitoring Node.js Applications with OpenTelemetry, Prometheus, and Grafana
As developers, we strive for performance and resilience in our applications. Effective monitoring is key to achieving these goals. This article outlines a powerful monitoring stack using OpenTelemetry for tracing, Prometheus for metric collection, and Grafana for visualizations. By implementing this setup, you can gain deep insights into your application's health, troubleshoot issues faster, and ensure a seamless user experience.
The setup consists of three key technologies: OpenTelemetry for tracing, Prometheus for metric collection, and Grafana for visualization. With this stack, you can monitor specific endpoints, visualize key metrics, and optimize resource usage. This setup is widely adopted in production environments to monitor microservices, applications, and infrastructure.
