Node.js applications require monitoring to identify bottlenecks and optimize resource utilization. Key concepts include application metrics, which track CPU usage, memory, disk space, request latency, and error rates. Node.js monitoring tools like New Relic, Datadog, and Prometheus can collect and analyze these metrics, helping developers ensure high availability and user experience.
Performance monitoring and APM tools are crucial for application success, providing a comprehensive view of an app's inner workings to make data-driven decisions, track response times, throughput, and error rates to identify bottlenecks and optimize resource allocation.
