Which service provides a centralized dashboard to monitor performance metrics and alerts across all Azure resources?

Azure Monitor is the correct answer because it provides comprehensive monitoring of your Azure resources, applications, and operating systems. It collects and analyzes telemetry data, such as metrics and logs, from various sources, offering a centralized dashboard for performance monitoring, health tracking, and alert management. This allows you to identify issues, understand resource utilization, and respond to critical events. Azure Advisor provides personalized recommendations for optimizing Azure deployments but doesn't offer real-time monitoring dashboards. Azure Blueprints help define repeatable sets of Azure resources that adhere to organizational standards, focusing on deployment consistency rather than monitoring. Azure Policy helps enforce organizational standards and assess compliance, which is about governance, not performance monitoring.
