Model Monitoring

Model monitoring is the continuous observation of a deployed model's behavior, quality, and operational health in production — capturing the metrics, alerts, dashboards, and traces that let an organization know whether the model is doing what it was deployed to do, and detect problems before they propagate to users. For LLM applications, monitoring spans four dimensions: operational (latency, throughput, error rate, cost per query, token consumption), quality (LLM-as-judge scores, structured-output validation pass rate, citation accuracy, hallucination flags), safety (policy violations, prompt-injection detections, jailbreak attempts, refusal rate), and engagement (user satisfaction signals — thumbs up/down, conversation length, escalation to human, retry rate). The tooling landscape combines general-purpose observability (Datadog, New Relic, Prometheus, Grafana, OpenTelemetry) with LLM-specific platforms (LangSmith from LangChain, Langfuse open-source, Helicone, Phoenix from Arize, Weights and Biases Weave, Honeyhive, Patronus AI, LlamaTrace). A typical setup: every LLM call emits a trace with the prompt, response, model, latency, token counts, retrieval context, user ID, session ID, and tool calls; traces are aggregated into spans for multi-step workflows; quality scores are computed asynchronously by sampled human review or automated judges; dashboards show distributions, drifts, and alerts. The OpenTelemetry GenAI semantic conventions (released 2024-2025) standardize the trace schema across vendors. For governance, monitoring telemetry feeds the audit trail required by ISO 42001 monitoring controls, EU AI Act post-market monitoring obligations, and NIST AI RMF Measure function. AI governance teams pair real-time monitoring with periodic audit — daily dashboards for operations, weekly reviews for quality trends, quarterly audits for compliance evidence.

Monitoring from 25 years of operational telemetry: Centralpoint has emitted operational telemetry, audit events, and engagement signals from enterprise content for 25 years — extending that telemetry to LLM prompts, responses, and quality scores is the same observability infrastructure with new event types. Telemetry stays on-premise, tokens meter per skill, and monitored chatbots deploy through one line of JavaScript.
