Agentic Observability: OpenTelemetry & Tracing Guide
Prerequisite: Familiarity with high-throughput inference engines and serving metrics covered in Part 8 — Inference Optimization: vLLM & PagedAttention. Answer-first: Black-box multi-agent runtimes obscure internal reasoning loops, tool invocation latencies, and rapid token cost accumulation across production clusters. Implementing OpenTelemetry GenAI semantic conventions captures hierarchical span trees, TTFT metrics, and per-tenant cost attribution in real time, enabling automated drift detection, prompt regression testing, and deterministic enterprise auditability across all infrastructure. ...
