Implement Dynamic Performance Monitoring Middleware for Node.js Microservices

performance middleware microservices monitoring nodejs
Prompt
Design a comprehensive performance monitoring middleware for a distributed microservices architecture using Node.js. The middleware should automatically capture and log detailed metrics including request latency, memory usage, CPU consumption, and error rates for each service endpoint. Implement adaptive sampling strategies to minimize performance overhead, with configurable thresholds that trigger detailed tracing for anomalous requests. Include a mechanism for real-time dashboard generation and support for multiple export formats (Prometheus, OpenTelemetry).
