With NUT v2.8.3 (in release candidacy cycles now) there are new notifications for OVER(load), TRIM and BOOST events - if raised by device and driver.
Other than that, you might have to script something around `upsc` or use the C/perl/python/... client bindings. For regular logging specifically, see also `upslog` client - it got some attention over the past couple of releases. But note it logs whatever data points you select at intervals you specify, to a file or stdout. Perhaps you can pipe it to a script that would look for your definition of low voltage, might be more efficient than of spawning `upsc` for every lookup. Hope this helps, Jim Klimov On Wed, Apr 16, 2025, 22:44 Bill Barnett via Nut-upsuser < [email protected]> wrote: > During periods of high power demand, I have noticed that the ups input > voltage drops.
