The APC PowerChute utility will only run in Windows, but if you are running Ubuntu Linux (or some variation thereof) you can have pretty much the same thing by following the instructions in this article:

Configuration of APC UPS in Ubuntu (Tech-Niche)

The article suggests you install gapcmon but you probably don’t need to do that, because Ubuntu already includes a Power Statistics utility that works well enough for most users.

If you have problems getting it to work, make sure the USB cable is plugged into the correct jack on the UPS (with some models it’s easy to plug it into a network cable jack by mistake). From the command prompt issue the command lsusb and it will tell you what is connected to your USB ports — you should see an entry for “American Power Conversion Uninterruptible Power Supply” if the cable is correctly connected.
