A team configures Application Insights sampling. What does adaptive sampling adjust automatically?
- A Log Analytics workspace retention
- B The fraction of telemetry items tracked, reducing volume and cost while preserving statistical accuracy (correct answer)
- C Alert thresholds
- D Metric aggregation intervals
Shortcut: Adaptive sampling dynamically adjusts the sampling percentage to maintain a target telemetry volume. It ensures representative data at reduced cost, preserving operation counts for accurate failure rate calculations.
