I'm afraid I don't have an APC UPS to know its quirks, but in my case I have 
these running:

upsd
upsdrv
upslog
upsmon


Is it that the UPS does not recycle the power, or is it that the PC does not 
reboot after power is restored?  Does the PC reboot if you pull and reinsert 
its mains plug?

WARNING:  don't just pull the plug in a fully working system to avoid fs 
corruption - Press something r e i s u  in sequence while holding 
Ctrl+Alt+SysRq and then pull the plug.  If the PC's BIOS is configured 
correctly it should reboot as soon as you reconnect the mains supply to it.

Have a look here if you haven't seen this section already:
