Do you just need monitoring or do you need control/automated operating system shutdown?
Network UPS Tools (NUT) is a really good option. Does USB, serial, and SNMP and covers a ton of UPS makes and models. You’ll find that a lot of SANs and other storage devices that “just work” when you connect a USB cable are probably using NUT under the hood.
If you just need SNMP monitoring, pretty much any opensource network management system could be made to work.
Observium is a good free tool for monitoring. It is one of those “just works” sort of monitoring systems that was easy to get started with. When I set it up I used the Turnkey Linux version , which makes provisioning even easier.
Nagios is really extensible.
Zabbix is a tool I’ve seen some of our customers using (although I think moreso with PDUs, but either should be achievable via SNMP).
LibreNMS is another opensource monitoring solution that is fairly popular.
There is a lot you can do with Net-SNMP and bash scripts too.
In a nutshell, if you have an SNMP-manageable UPS, whatever SNMP manager you use for your other devices can probably fit. Let me know if you need some more information (regardless of the UPS vendor you’re looking to monitor), this overlaps a bit with some topics I am looking into now.

Does anyone have any recommendations for Open Source UPS monitoring software?

Hello
I'm looking for some solution to power down all devices while my UPS will be low on battery.
Mainly I expect tool to loggin via SSH and run shutdown command, but additional value would be Windows support.
App/WebApp/Script would be running on Raspberry Pi4, also Zabbix is running there.
I'm running following services, which require to be shutdown: 1 x FortiGate firewall 20 x Ubuntu VM 2 x ESXi server 3 x Windows VM 2 x Mikrotik VM 2 x Synology NAS
Please advise if you know any software which would meet my requirements or maybe keywords to search for.
I'm about creating my own script for this in Python, but well developed service is preferred :)
Does anyone have experience with a good Open Source UPS management application? We just bought several Liebert UPS systems and I'm looking for a good way to centrally manage them. Obviously Nform is an option, just looking for others.
It might not be the right solution for your situation (NUT as mentioned by the other answer is right for you), but a common solution for *nix system is apcupsd. It links to most UPSs (they have a list) and will do remote communication (to shutdown multiple systems connected to the same power source). Also, several big server equipment brands are actually rebadged APC units (such as HP UPSs).
The only way I know of doing this is Network UPS Tools - http://www.networkupstools.org/ as you mentioned but I don't really know much about *nix/bsd so there may be others. NUT does the job and is compatible with some Eaton units.
Although I've also read people mentioning using a windows machine plugged into the ups to inform *nix boxes they should shut down but I wouldn't know where to start on that.
Lately I have been playing a lot with UPS devices. Both using NUT and APCUPSD, but also trying to do my own work.
The result of some personal experimentation was my own tool called sups (simple ups)
Using it is as simple as extracting the executable (ideally somewhere in your path) and then running it like
sudo ./sups
sudo is probably required because more than likely the dev file is owned by root
The application looks on its own for HID compatible devices under /dev and tries to connect to the first one that it finds.
You can define your own device using the --port argument
sudo ./sups --port /dev/usb/hiddev1
If you want to shutdown the local machine below a certain battery level, you can use the --monitoring argument. The default threshold is 50% as this is the minimum safe level for cheap lead acid batteries. But you can also define your own threshold using the argument --threshold and passing the percentage. Like
sudo sups --monitoring --threshold 30
There is no daemon or service mode, so for automated shutdown the application has to be run through root's cron using something like
* * * * * sups --monitoring --threshold 45
The application does not support any low level communication with the device drivers. This was a deliberate choice. It restricts communication with fancy UPS functions, but also allows the application to be written in a higher level language that is easier to follow and maintain.
So far the app is only tested with only a few UPS devices that I have access to
So I would appreciate any feedback or corrections
You can use the --debug argument to see more information about what data was received from the device and how it was parsed.
The reasoning behind the app was to create a tool that is functionally complete but simple to use with 0 configuration even with multiple UPS devices, while at the same time being easy to maintain.
You can find the code and the executable, along with detailed instructions about the application and HID in general, under the github repo
