Graceful Shutdown on Power Outage

[okynnor]

Hi,
I have a good APC UPS attached to TrueNAS. The UPS power lasts about 6+ hours. Usually, this sufficient. When the grid's power outage lasts longer, then we have a problem. Is there a way to setup TrueNAS to gracefully shutdown when it monitors that the UPS power is about to be depleted? The UPS, an older XL model, does have monitoring capabilities but just needs software to poll it. Is there a feature/program that can be installed onto TrueNAS?

TrueNAS includes the NUT (Network UPS Tools) package - if your APC is on the NUT HCL (https://networkupstools.org/stable-hcl.html) it should be capable of being managed, and you can then set a trigger of "UPS reaches low battery" or a time-delay based on "UPS goes on battery" if you want to adjust the grace period manually.

Old docs but still good docs:

TrueNAS includes NUT as a Service - that has a documented capability of shutting down the attached server on either "low battery" or "on going onto battery".

Thanks all for your help so far. I would like to ask if there's docucmation to get XCP-NG to gracefully shutdown just as the document only described the topic for ESXi and WinNUT.
