The correct choice for reviewing diagnostics data is Azure Application Insights. This service is designed to monitor the performance of applications, offering extensive capabilities for tracking metrics, requests, failures, dependencies, and custom events. Azure Application Insights also provides rich insights through telemetry data, making it easier for developers and IT professionals to understand how applications are performing in real time.

This service integrates seamlessly with various platforms and programming languages, allowing for end-to-end monitoring of applications deployed in Azure or in on-premises environments. The data reviewed through Azure Application Insights can include user behavior, application exceptions, and performance metrics, thus providing a comprehensive overview of the application's health and usage.

While Azure SQL Analytics and other options may offer some level of monitoring or health reports, they are more specialized and not as versatile in scope as Azure Application Insights when it comes to reviewing broad diagnostics data across applications.
