Tracing

Prerequisite: Familiarity with the concepts introduced in Part 5 — Security. Review it first if the terminology in this part is unfamiliar. Part 6 — MCP Observability & Tracing: Auditing the Control Plane Answer-first: Operating Model Context Protocol (MCP) servers without telemetry logging creates compliance vulnerabilities (violating OWASP MCP08: Lack of Audit & Telemetry). Instrumenting MCP servers with vendor-agnostic OpenTelemetry (OTel) tracing captures JSON-RPC 2.0 tool execution durations, argument metadata, and error rates in real-time Prometheus dashboards. ...

Prerequisite: Familiarity with the concepts introduced in Part 8 — Inference Optimization Vllm. Review it first if the terminology in this part is unfamiliar. Part 9 — Agentic Observability: OpenTelemetry, Tracing & Cost Monitoring Debugging traditional microservices involves tracking HTTP status codes and database query latency. Debugging AI agent architectures demands tracking non-deterministic reasoning chains, LLM API token costs, prompt context inflation, and multi-turn tool loops. Without standardized distributed tracing, identifying why an agent query took 8.5 seconds or cost $1.20 per invocation becomes an impossible troubleshooting task. ...
