Telemetry volume is driving unacceptable cost. Which technique reduces ingestion while preserving representative data?
- A Disable Application Insights
- B Adaptive or fixed-rate sampling (correct answer)
- C Reduce retention only
- D Delete the workspace
Shortcut: Sampling discards a proportion of telemetry while preserving statistical accuracy, and keeps related items together so traces remain coherent. Retention changes storage cost, not ingestion cost.
