RADAR is a four-stage system for catching gray failures, which are partial, silent outages that can cost customers and revenue without being detected by traditional monitoring systems. The four stages are: (1) reliability metrics, (2) anomaly detection, (3) alerting, and (4) root-cause analysis, which can be applied to any metric, including billing, conversion, or model performance. RADAR can be built on Databricks using native components and an AI-agent scaffold, allowing developers to catch gray failures in minutes at over 90% precision and 95% faster discovery. AI summary
