.NET Backend Observability & Telemetry Integration

.NET Backend Observability: Telemetry Integration & Performance Optimization Client E-commerce platform with high-load .NET 8 backend Challenge The .NET backend had no observability — no distributed tracing, no centralized metrics, no structured logging. Finding slow requests required manual log digging. The team needed full OpenTelemetry integration: trace propagation from Ingress through .NET to downstream services (PostgreSQL, Redis, RabbitMQ, HTTP upstreams), automatic slow-query detection, and a path to optimize P99 latency.
