- **Event Trace**: Collects info on specific **state changes** via probes; has low overhead (~5%) but shouldn't be used in sensitive areas like interrupt handlers.
|
|
- **Sampling**: **Polls the system state** periodically; accuracy is proportional to overhead (higher accuracy requires more frequent polling).
