Prerequisite: Familiarity with distributed tracing and observability metrics established in Part 9 — Agentic Observability: OpenTelemetry & Cost Monitoring. Answer-first: Manual spot-checking cannot prevent silent prompt regressions, context hallucination, or retrieval degradation in enterprise production releases. Implementing automated CI/CD quality gates powered by Ragas and multi-pass LLM-as-a-Judge arbitration evaluates the RAG Triad - Faithfulness, Context Precision, and Answer Relevance - blocking non-compliant model releases and maintaining 99.2% factual groundedness across all corporate environments. ...

Answer-first: Enterprise GenAI observability establishes end-to-end visibility into autonomous agent workflows by standardizing on OpenTelemetry semantic conventions v1.30, capturing distributed execution traces, token consumption velocity, and model hallucination metrics across private gateways and local models, enabling engineering leaders to enforce strict operational latency SLAs and budget caps across production cloud infrastructure. Prerequisite: Familiarity with OpenTelemetry tracing standards, Prometheus metrics, Grafana dashboards, and FinOps cloud accounting. 1. The Fatal Blind Spot of Traditional APM In microservices architectures, Site Reliability Engineers (SREs) rely on the Four Golden Signals: Latency, Traffic, Errors, and Saturation. ...
