The selected answer is correct because Metrics in Azure provides comprehensive insights into the performance and health of your virtual machines. Metrics allow users to monitor various aspects such as CPU usage, memory consumption, disk I/O, and network traffic, helping administrators understand the operational state of their resources in real time.

Using Metrics, you can set up alerts based on performance thresholds, visualize data trends over time, and make informed decisions regarding scaling or optimizing your virtual machines. This functionality is crucial for maintaining optimal performance and resource utilization, making it the most suitable feature for tracking VM performance.

While Application Insights is also important for monitoring and diagnosing application performance, it is more focused on applications rather than directly on the performance of virtual machines. Health alerts can notify users about specific issues affecting their resources, but they do not provide ongoing performance metrics. Compliance Manager is related to managing compliance with regulatory requirements and does not pertain to performance monitoring.
