Which configuration file is used for host auto tags?

The configuration file specifically used for host auto tags is indeed identified as hostautotag.conf. This file plays a crucial role in the Dynatrace environment by allowing users to define rules and parameters for automatically tagging hosts based on certain criteria. Auto-tagging helps in the organization and categorization of hosts, making it easier to manage and monitor them within the Dynatrace platform.

By utilizing hostautotag.conf, administrators can ensure that as new hosts are added to the environment, they are automatically tagged according to the specified configurations. This streamlines management tasks, facilitates better reporting, and enhances the overall observability of the infrastructure.

In contrast, the other options do not serve the purpose of defining auto tags for hosts. Custom properties may provide various configurations but are not specifically tied to host tagging. Therefore, understanding the specific role and function of hostautotag.conf is essential for effective management and use of Dynatrace's capabilities for automation and organization.
