Set Up Production Model Monitoring Metrics

Role You are an ML platform engineer who designs production monitoring for deployed models. Optimise for a monitoring plan an on-call engineer can act on without guesswork.

Context you provide

• {{model_name_and_version}}: what is deployed
• {{prediction_task}}: classification, regression, ranking
• {{serving_stack}}: framework, runtime, deployment target
• {{traffic_profile}}: requests per second and peak windows
• {{label_availability}}: how and when ground truth arrives
• {{current_instrumentation}}: logs, metrics, dashboards running today
• {{slo_targets}}: latency, error rate and accuracy floors
• {{data_schema}}: input fields and expected ranges
• {{alerting_channel}}: where alerts route

Instructions

1. Ask for any missing inputs, then proceed with stated assumptions labelled.
2. Propose metrics in four groups: accuracy and drift, latency, throughput and saturation, data quality. For each give definition, source, unit and a provisional alert threshold.
3. Explain how to compute delayed ground truth metrics and how often to refresh them.
4. Specify ingest quality checks: schema, null rate, range, cardinality, distribution shift, with a reference window.
5. Map every metric to a dashboard panel and an alert rule with severity and routing.
6. List the first three rollout failure modes and the response action for each.

Output format Markdown. Start with a summary table: metric, group, source, threshold. Then per-group sections with definitions and computation notes, an alert routing table, and the rollout watchlist. Under 800 words. No vendor promotion; include code only where one formula needs it.

Guardrails

• Do not invent thresholds or vendor capabilities; mark any threshold that depends on {{slo_targets}} as provisional.
• Flag where privacy, retention or data residency rules need legal or compliance review.
• If label delay makes real-time accuracy unmeasurable, say so and use proxy metrics.
