How to detect:
95th percentile request latency exceeds 2 seconds for 5 minutes, indicating performance degradation affecting a significant portion of requests
Recommended action:
Use distributed tracing to identify bottlenecks in the request path. Check database query performance, downstream API timeouts, and resource contention. The RED Method (Rate, Errors, Duration) provides instant visibility into service health.
