Which command is used to clear the custom host name in Dynatrace OneAgent?

The command used to clear the custom host name in Dynatrace OneAgent is the one that specifies an empty string for the host name parameter. This effectively removes any custom name that has been set for the host. By using the syntax --set-host-name="", you are instructing the OneAgent to erase the specific host name, resulting in it falling back to its default name, which is typically derived from the host's machine name or other identification methods.

Setting the host name to an empty string is a common method in command-line interfaces for clearing previously assigned values. This clears the configuration for that specific attribute without needing to provide a new name. It's important to note that clearing the host name doesn't impact the OneAgent's functionality; it simply reverts the identification process back to the default behavior.

The other commands either set a new host name, manage host properties, or retrieve information about the host ID, but none of these actions would achieve the goal of clearing the custom host name.
