What is a limitation of deep monitoring rules for process groups?

The correct choice highlights that deep monitoring rules for process groups specifically affect only the applications that have the OneAgent installed. This is significant because OneAgent is responsible for collecting real-time monitoring data from the monitored applications. If an application does not have the OneAgent deployed, it will not be subject to the deep monitoring rules, and as a result, it won't benefit from the insights and data collection those rules provide. This limitation emphasizes the dependency on the presence of OneAgent for effective monitoring, which is crucial for organizations looking to implement comprehensive monitoring strategies across their applications.

In contrast, the other options describe aspects that do not accurately reflect the limitations of deep monitoring rules for process groups. For instance, defining rules for any number of processes does not imply any inherent limitation. Similarly, the assertion about impacting all application integrations may suggest a broader application of these rules beyond what is true, while suggesting that they can only be utilized in on-premise setups mischaracterizes the flexibility of Dynatrace's monitoring capabilities, which extend to cloud and hybrid environments.
