Alerting Strategy and Incident Response Questions

Design alerting strategies and incident response practices that turn observability signals into actionable operations. Topics include alert design and classification, threshold versus anomaly detection, preventing alert fatigue, escalation and on call flow, runbook and playbook design, integrating alerts with incident management, post incident review and blameless postmortems, and how monitoring and observability feed incident detection and mean time to resolution improvements. Includes designing alerts for different domains and thinking through what runbooks and context to provide to responders.

Propose an ML-specific alerting and SLA governance model across product teams: how to define SLOs for ML services, mechanisms to report violations, escalation for non-compliance, and incentives to ensure teams maintain monitoring hygiene without undue overhead.

For a binary classification model deployed as a REST API, list the top 8 observability signals you would monitor to operate the model safely in production. For each signal, give a one-sentence justification and a possible alert condition example.

HardSystem Design

0 practiced

Architect an automated incident triage system that runs safe diagnostics and summarizes results before paging humans. The system should pull metrics, run schema checks, compare recent model predictions to baselines, and attach reproducible artifacts to the incident. Describe components, data flows, failure modes, and safety constraints for any automated actions.

Describe a reproducible procedure to select alert thresholds for a key model metric (e.g., precision@k) using historical data and business cost of false positives and false negatives. Include evaluation steps, simulation of operational workload, and guardrails for seasonality.

You want to surface explainability signals in alerts: e.g., sudden changes in top-3 SHAP feature importances for a model serving high-stakes decisions. Describe how you would compute, store, and alert on these explainability signals at scale without blowing compute cost or creating noisy alerts.
