Which Azure service provides visibility into resource performance metrics and logs across multiple regions?

Azure Monitor is the correct answer because it provides comprehensive data collection, analysis, and visualization of telemetry from your Azure resources, on-premises environments, and other clouds. This includes performance metrics, activity logs, and diagnostic logs, enabling you to gain deep insights into the health and performance of your applications and infrastructure across various regions. Azure Advisor offers recommendations for optimizing resources, but doesn't provide real-time monitoring. Azure Blueprints helps define repeatable sets of Azure resources, ensuring compliance and consistency, not performance monitoring. Azure Policy enforces organizational standards and assesses compliance, but doesn't collect performance metrics.
