What must be done to perform a complete uninstallation of Dynatrace OneAgent on Linux?

To perform a complete uninstallation of Dynatrace OneAgent on Linux, backing up configuration files is an important step. This step ensures that any custom settings or configurations that were applied to the OneAgent can be retained for future use, either for reinstallation or for analysis purposes. Proper management of configuration files allows users to maintain consistency across environments or easily recreate the setup, should the need arise to reinstall the agent.

The other options do not provide a comprehensive approach to complete uninstallation. Simply uninstalling the OneAgent package may remove the agent but would leave behind configurations and logs that might be important for troubleshooting or future reference. Removing the user running OneAgent may not even be necessary or relevant to the uninstallation process, as the user could be associated with other systems or services. Deleting all log files may clean up space, but it does not guarantee that a thorough uninstallation is achieved, especially if configuration files remain that might create conflicts or confusion if the agent is reinstalled. Thus, focusing on backing up configuration files is crucial for effective management before a complete uninstallation.
