Which feature allows an Azure SQL Database to audit and log events?

The feature that allows an Azure SQL Database to audit and log events is SQL Database Auditing. This capability is specifically designed to track database events, such as logins, data changes, and access to sensitive data, thus providing a comprehensive view of the database's activity.

SQL Database Auditing helps organizations meet compliance requirements by logging events that can then be analyzed for security and auditing purposes. The audit logs can be stored in several locations, including an Azure storage account, and can be integrated with Azure Monitor for further analysis and alerting.

While Performance Insights, SQL Analytics, and Azure Monitor provide valuable information on performance and health monitoring, they do not specifically focus on auditing and logging events within a database context. Performance Insights optimizes database performance, SQL Analytics helps in understanding query performance and resource utilization, and Azure Monitor provides a platform for monitoring the overall Azure environment, but none of these are tailored specifically for auditing database changes and user activities like SQL Database Auditing is.
