Which of the following is NOT a feature of the Dynatrace OneAgent?

The choice indicating that executing synthetic monitor execution is not a feature of the Dynatrace OneAgent is correct. The OneAgent is primarily designed to monitor applications and services by automatically collecting real-time performance and health data, including metrics related to CPU and memory usage and tracing transactions from start to finish.

Synthetic monitoring, however, involves the execution of scripted user interactions to simulate user behavior and is typically handled by a different component in Dynatrace known as the Synthetic Monitoring solution. While OneAgent provides essential support for observing real user transactions and performance, synthetic monitoring is a distinct feature that is not directly executed by the OneAgent.

In summary, the OneAgent's core functionalities include reporting data, collecting vital metrics, and tracing transactions, whereas executing synthetic monitor scripts is outside its scope and is managed separately within the Dynatrace ecosystem.
