Integrate Metrics with Prometheus and Tracing with OpenTelemetry

Objective

Collect and expose metrics for monitoring using Prometheus. Integrate tracing using OpenTelemetry to provide distributed tracing capabilities across the application.

Description

Metrics Collection

• Use the prometheus crate to collect metrics such as request counts, error rates, and latency.
• Implement counters, histograms, and gauges as needed.
• Instrument key parts of the code to record metrics.

Expose Metrics Endpoint

• Use Hyper to create an HTTP endpoint ( /metrics) that serves Prometheus metrics.

Integrate Tracing

• Use the tracing and tracing-subscriber crates to add tracing instrumentation.
• Integrate tracing-opentelemetry to export traces to an OpenTelemetry collector.
• Configure exporters like Jaeger
