What does the Dynatrace OneAgent modify during installation regarding process management?

The Dynatrace OneAgent modifies the core pattern configuration during installation to ensure that it can effectively monitor and manage the systems it is deployed on. By handling core dumps appropriately, the OneAgent can collect critical diagnostic information when applications experience failures or crashes. This is essential for providing insights into application performance and for troubleshooting issues, as it allows the Dynatrace platform to analyze the circumstances surrounding a failure, thus enhancing overall system reliability and user experience.

The other options do not accurately represent the specific modifications made by Dynatrace OneAgent. Adjusting CPU affinity settings, optimizing memory allocation, or limiting resource usage based on service type are not core functions or changes that the OneAgent performs during its installation. Instead, the focus is on gathering and analyzing operational data, which is facilitated by setting up proper core dump management.
