What command allows you to set a custom host name in Dynatrace OneAgent?

The command that allows setting a custom host name in Dynatrace OneAgent is designed specifically for this purpose, making it straightforward for users to customize their environment. The structure of the command reflects that it is invoking the OneAgent control tool, oneagentctl, with a specific action flag (--set-host-name) followed by the desired custom name (myhostname). This command directly targets the functionality needed for changing the hostname, enabling administrators to ensure that the displayed host name accurately reflects their organizational naming conventions or specific identification purposes.

In contrast, the other options serve entirely different functions within the OneAgent control toolkit. One concerns the removal of a host property, another is about assigning a host to a group, and the last deals with retrieving system access log permissions. None of these options relate to altering the host name, which is the primary requirement of the question. Therefore, recognizing that the ability to customize the host name is encapsulated in the specific command provided in the correct answer is key to managing and defining host identities within Dynatrace effectively.
