Which command clears the host group assignment in Dynatrace OneAgent?

The command that clears the host group assignment in Dynatrace OneAgent is the one that uses the syntax --set-host-group= without specifying a group name. When this command is executed, it removes any previous association of the host with a specific host group, effectively clearing the host group assignment.

Using the command with an equal sign but no value indicates to the system that the intent is to not assign the host to any specified group, which is precisely how one would clear an existing assignment. This functionality is crucial for managing host group memberships dynamically as the operational environment changes.

Other options presented serve different purposes. For example, setting a host group with a specific name would assign the host to that group but does not clear any existing groups. The command to get the host ID is merely an informational command and does not modify any configurations, while setting host properties is unrelated to the concept of host groups altogether.
