This menu is divided in two sections, the APC UPS Status table and APC UPS Response strings. UPS monitoring is only available for APC uninterruptible power supplies with USB connection compatible with APC’s smart protocol library. The UPS Monitor library is included by default only in the Mega-VPN and AIO builds.

For more details, see: https://networkupstools.org/protocols/apcsmart.html

To establish a successful connection, first enable USB 1.1 support (OHCI) and Run APCUPSD Daemon in the USB Support menu.

The table shows UPS model name, status, charge level, line voltage, load, estimated run time.

The list of strings has all the information retrieved from UPS.

This information is the same as in other tools (e.g. apcupsd utility daemon for controlling APC UPSes on a local network windows machine, http://www.apcupsd.org/)

For debugging purposes, included below is a snippet for UPS Monitoring successful startup log entries.
