### AI overview

Uber describes a middleware-based system that correlates caller and downstream service failures to classify dependencies as fail-close, fail-open, or unknown. It uses production metrics to map failure propagation across its service mesh, aiming to analyze rare failures faster than sampled tracing allows.

### Source excerpt

Uber has developed an automated dependency analysis system that uses RPC middleware and production metrics to correlate caller and downstream failures. The approach classifies dependencies as fail-close, fail-open, or unknown and addresses limitations of sampled distributed tracing for rare failures across Uber's large service mesh. By Leela Kumili
