Minute-level monitoring lag loses transient anomaly context before diagnosis

Traditional monitoring systems with minute-level lag from polled metrics or log aggregation fail to capture transient issues in LLM inference. Inference request lifecycles are extremely short, and generation stalls often stem from ephemeral resource contention (PCIe bandwidth saturation, instantaneous throttling). By the time lagging metrics trigger alerts, anomalous requests have concluded and context has vanished.

Implement millisecond-level online monitoring and context capture. Deploy always-on lightweight monitoring that detects baseline deviations in real-time. Use event-driven collection rather than polling. Trigger synchronized on-demand deep tracing when anomalies are detected to snapshot execution context within the millisecond window before it vanishes.
