What is the command to show all tags in Dynatrace OneAgent?

The command to show all tags in Dynatrace OneAgent is indeed ./oneagentctl --get-host-tags. This command is specifically designed to retrieve and display the tags associated with the host monitored by OneAgent. Tags play a crucial role in organizing and managing different entities within Dynatrace, allowing users to categorize hosts, services, and applications based on specific attributes such as roles, environments, or functions.

The other options serve different purposes and are not suitable for displaying tags. For example, setting a host tag or modifying infrastructure-only settings does not pertain to retrieving existing tags. The primary function of this particular command is to provide visibility into the tags that have been assigned, aiding in effective monitoring and management within the Dynatrace environment. This makes it clear that option A is the appropriate choice for showing all tags in Dynatrace OneAgent.
