How are host groups assigned to a host?

Host groups in Dynatrace are assigned to a host automatically or during the installation process. This automatic assignment is part of the platform's design to streamline the organization of monitored resources. When a host is installed and the Dynatrace agent is applied, the system assesses the environment and assigns hosts to host groups based on predefined rules, like their role, characteristics, or underlying infrastructure.

This automated process reduces the need for manual intervention, ensuring that hosts are categorized efficiently right from the start. It also allows for dynamic adjustments; as the environment changes, hosts may be re-evaluated and re-assigned to different groups without requiring additional manual configuration.

The other options suggest methods that aren't inherent to Dynatrace's automatic management system, which is focused on scalability and minimal manual effort. Thus, the system's design emphasizes automation during installation as the primary method of group assignment for hosts.
