You are troubleshooting performance problems and need to investigate metrics related to Azure infrastructure. Which tool should you use to examine those metrics?

Azure Monitor is the correct tool because it provides comprehensive monitoring of Azure resources, including collecting and analyzing metrics, logs, and traces. It offers detailed insights into the performance and health of your infrastructure, enabling you to identify and troubleshoot performance bottlenecks. Azure Traffic Analytics focuses specifically on network flow data, not general infrastructure metrics. Azure Activity Log records control-plane events (who did what, when, and where), not performance metrics. Azure Advisor provides recommendations for optimizing Azure resources, but it doesn't directly display real-time performance metrics for troubleshooting.
