Correct answer & explanation
✓
Azure SQL Analytics (preview)
Azure SQL Analytics (preview) in Azure Monitor provides a consolidated monitoring solution for Azure SQL databases and managed instances, including detailed storage usage per database. Option A is wrong because Query Performance Insight focuses on query-level metrics like query duration and CPU usage, not per-database storage. Option B is wrong because Automatic tuning is a feature that automatically indexes and optimizes query plans, not a monitoring tool. Option C is wrong because Intelligent Insights provides proactive performance diagnostics and anomaly detection, but does not directly per-database storage monitoring. Therefore, only Azure SQL Analytics meets the requirement.
