RADAR: CATCH GRAY FAILURES WITH ANOMALY DETECTION

Summary from the TLDR DevOps newsletter

Gray failures allow specific service components to fail silently while health checks remain green, often leaking revenue for hours before detection. Databricks built a system called RADAR to catch these partial outages by identifying sudden spikes in user errors. The system reduced incident discovery time by 95% with over 90% precision. Users can build a similar detection pipeline on the Databricks platform using a template available on GitHub.
