You receive an alert 'prediction latency > 300ms' affecting a subset of requests. Describe the specific logs, distributed traces, telemetry, and sampling strategy you would use to determine whether the root cause is model computation, I/O or serialization, input preprocessing, or infrastructure degradation.
