FastAPI & OpenTelemetry: Distributed Tracing, Prometheus Metrics & Grafana
Diagnose millisecond-level bottlenecks across SQL queries, Redis calls, and LLM streaming responses with OpenTelemetry tracing.
Why Distributed Tracing Is Mandatory for AI Backends
When an API request takes 3 seconds, OpenTelemetry spans immediately reveal whether the bottleneck originated in the LLM streaming call, an unindexed database query, or Redis lock contention.
