What is the first step in defining a host naming rule?

The correct approach for defining a host naming rule begins with navigating to the appropriate settings within the Dynatrace platform. Accessing the Settings menu enables you to configure various monitoring options specific to host management. By going to the path of Settings > Monitoring > Host naming, you are directly accessing the feature that allows you to create or modify host naming rules. This is crucial because establishing these rules helps in organizing and managing hosts in your environment effectively, which is essential for clarity and efficient monitoring.

Other choices do not accurately reflect the initial step in the process. Selecting a host group is relevant but only comes after you have accessed the host naming settings. Installing the OneAgent software is a prerequisite for monitoring, but it does not specifically relate to defining host naming rules. Restarting the host is unrelated to the configuration of naming rules and does not facilitate the setup process in any way.
