What feature in MuleSoft allows for real-time monitoring?

C. Anypoint Monitoring is the correct choice because it provides comprehensive capabilities for real-time monitoring of APIs and applications within the MuleSoft ecosystem. This feature allows developers and operations teams to track the performance and health of various integrations in an organized way. It offers insights into traffic, error rates, response times, and more, helping to identify potential issues before they impact users.

Anypoint Monitoring enables users to create dashboards for visualizing metrics in real-time, set alerts for anomalies, and analyze logs, which are essential for maintaining the reliability and performance of applications. This level of monitoring is crucial for businesses demanding high availability and performance from their integrations.

While the other features mentioned may address aspects of development or monitoring, they do not provide the same comprehensive oversight of system health and performance metrics in a real-time context as Anypoint Monitoring does.
