Do you remember how did the UPS fail? I'm curious.
The UPS never actually failed, except for a time or two when the battery bank needed to be replaced.
Downstairs we have a couple of APC SmartUPS'es - they know very well when the batteries are due :-) They will sound an alarm, send an email and an SNMP alert and keep doing it until the battery "cartridge" is replaced. Once you pull out a cartridge, the entire bank is disabled, which reduces the runtime by 20%.
At home, I have a little 6kVA Eaton, it's a little more effort. To swap the batteries, you have to take the front off and switch it into bypass, for instance. With monitoring by NUT, I still get SNMP alerts though - not sure if it actually will complain about batteries, but it does complain if the runtime sinks below a certain threshhold.
Still, it is really off-topic.
We can talk about how to do the monitoring in openSUSE :-) Sometimes I see an applet on the desktop that says that the UPS battery is fully charged. Currently, on that "server" (yes, it runs XFCE because it does media server duties and I watch videos on it) reports on the battery of the Logitech keyboard, which is a nice new feature. It says it is at 50%. But it does not report on the UPS, which is connected via USB: <0.6> 2021-01-28T14:00:55.544877+01:00 Isengard kernel - - - [401782.992870] usb 1-2.2: USB disconnect, device number 6 <0.6> 2021-01-28T14:00:58.380821+01:00 Isengard kernel - - - [401785.828546] usb 1-2.2: new low-speed USB device number 7 using xhci_hcd <0.6> 2021-01-28T14:00:58.536862+01:00 Isengard kernel - - - [401785.987083] usb 1-2.2: New USB device found, idVendor=0665, idProduct=5161, bcdDevice= 0.02 <0.6> 2021-01-28T14:00:58.536906+01:00 Isengard kernel - - - [401785.987101] usb 1-2.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 <0.6> 2021-01-28T14:00:58.536910+01:00 Isengard kernel - - - [401785.987113] usb 1-2.2: Product: USB to Serial <0.6> 2021-01-28T14:00:58.536913+01:00 Isengard kernel - - - [401785.987122] usb 1-2.2: Manufacturer: INNO TECH <0.6> 2021-01-28T14:00:58.536915+01:00 Isengard kernel - - - [401785.987132] usb 1-2.2: SerialNumber: 20100826 <0.6> 2021-01-28T14:00:58.548845+01:00 Isengard kernel - - - [401785.997855] hid-generic 0003:0665:5161.0007: hiddev97,hidraw2: USB HID v1.00 Device [INNO TECH USB to Serial] on usb-0000:00:14.0-2.2/input0 <1.6> 2021-01-28T14:00:58.684152+01:00 Isengard mtp-probe - - - checking bus 1, device 7: "/sys/devices/pci0000:00/0000:00:14.0/usb1/1-2/1-2.2" <1.6> 2021-01-28T14:00:58.685372+01:00 Isengard mtp-probe - - - bus: 1, device: 7 was not an MTP device The log reports on the chip that converts from the internal rs232 port to USB, not really on the UPS.
