How can you display your host ID in Dynatrace OneAgent?

To display your host ID in Dynatrace OneAgent, using the command ./oneagentctl --get-host-id is the correct approach. This command is explicitly designed to retrieve and show the unique identifier associated with the host where the OneAgent is installed.

The host ID is crucial for tracking and managing monitoring data within the Dynatrace platform, as it uniquely identifies each monitored host, allowing you to correlate performance metrics and insights specifically to that host.

The other commands mentioned serve different purposes. Setting a host group, changing the host name, or defining host properties are actions that modify configurations related to the host but do not provide information about its ID. Thus, they do not align with the goal of displaying the host ID. The specific functionality of --get-host-id distinguishes it as the correct choice for this task.
