What is required to change how processes are identified and grouped in process group detection?

To change how processes are identified and grouped in process group detection, it is necessary to restart the processes. Process group detection relies on unique properties of running processes to categorize them effectively. When you alter the configuration or rules that dictate how these processes are grouped, a fresh start allows the system to re-evaluate and apply these new settings accurately.

Restarting the processes enables the Dynatrace environment to recognize any changes in identifiers or attributes that define how processes should be categorized, ensuring that the updated groupings take effect immediately. This is critical because processes may cache their grouping information, and without a restart, they could continue to operate under old configurations.

In contrast, options such as restarting applications, manual reconfiguration of rules, or installing additional software would not directly ensure that the changes in process identification take effect as intended without the associated process restarts.
