I just experienced a 2 hour power failure, which was long enough for my APC UPSs to power down. However, I have one UPS on my Linux computer and the other on my pfSense firewall. I noticed that the firewall one, which runs on FreeBSD, provided more info that the one on Linux. Any idea why that may be? Both UPSs are the same model and age.

Why the difference with the Linux system.?
