A multi-tier application uses Azure Web Apps for the front end and Azure SQL Database for the back end. You must capture and centrally store telemetry to allow ad-hoc queries for baselines, trigger alerts when metrics exceed those baselines, and retain application and database metrics in one location. Which service should you recommend?

Azure Log Analytics is the correct choice because it is a centralized logging service within Azure Monitor designed for collecting, querying, and analyzing logs and metrics from various Azure resources, including Azure Web Apps and Azure SQL Database. This allows for ad-hoc queries, setting baselines, and triggering alerts based on collected data, fulfilling all requirements. Azure Event Hubs is a data streaming platform, not primarily for centralized logging and analysis. Azure SQL Database Intelligent Insights focuses specifically on SQL Database performance, not the entire application stack. Azure Application Insights is excellent for application performance monitoring (APM) and telemetry, but Log Analytics provides a broader, more centralized platform for all types of logs and metrics across different services, making it more suitable for consolidating both application and database metrics in one location for comprehensive analysis and alerting.
