Which Dynatrace metric provides an overview of overall service usage and performance?

The metric that provides an overview of overall service usage and performance is network traffic. This metric reflects the volume of data transmitted and received by applications and services, which is crucial for assessing their efficiency and responsiveness. Monitoring network traffic allows organizations to understand how performance is impacted by varying data loads, identify bottlenecks, and optimize the user experience based on traffic patterns.

Other metrics like memory usage, disk I/O, and CPU utilization, while important in their own right, focus more on the resource utilization of the server or application itself rather than providing a holistic view of service usage across the entire network. These metrics can contribute valuable information regarding the performance and operational efficiency of an application, but network traffic specifically connects the application performance directly with user interactions and service demand, highlighting overall service utilization.
