When an administrator runs esxtop and no output is displayed, pressing 'f' allows them to configure which metrics or fields to display in the esxtop interface. By default, esxtop may not have any fields selected to show data, leading to the appearance of no output. By entering the configuration mode using the 'f' key, the administrator can enable various performance metrics relevant to the ESXi host, thus allowing important data to be viewed and analyzed.

This interactive capability is a key feature of esxtop, facilitating customizing the information displayed to suit the administrator’s needs. Being able to select and toggle fields ensures that the administrator can monitor specific performance indicators effectively.

The other choices, while they may seem plausible, do not directly address the issue of no output in esxtop. Restarting the ESXi host or running esxtop with elevated privileges is unnecessary for resolving the display issue. Similarly, using the command resxtop pertains to a different context (remote monitoring) and wouldn't apply to the situation of no output. Thus, configuring the display fields is the most appropriate solution.
