Which OCI service provides application performance monitoring?

The correct choice is Oracle Application Performance Monitoring because this service is specifically designed to monitor and analyze the performance of applications running on Oracle Cloud Infrastructure and other environments. It provides detailed insights into application performance metrics, allowing users to diagnose issues, optimize performance, and enhance user experiences effectively. The service offers features like tracing requests, monitoring transaction throughput, and identifying slow transactions, which are essential for maintaining high application performance.

Other services listed have their specific functions but do not focus primarily on application performance monitoring in the same comprehensive and targeted manner. For instance, Oracle Cloud Monitoring provides general monitoring capabilities for various cloud resources and infrastructure components rather than specifically targeting application performance. The OCI Health Check Service is used to determine the availability of resources and ensure they are functioning properly, but it does not provide in-depth performance analytics. OCI Performance Insights typically relates more to database performance rather than application performance monitoring as a whole.

In summary, Oracle Application Performance Monitoring is tailored to provide comprehensive tools and insights needed for effectively managing and enhancing application performance.
