Line-voltage provided by attached UPS, with NUT (Network Ups Tools) providing data access, is logged by a systemd-timer every 10 minutes. The log file is parsed by a C-program invoked by PHP to obtain the current line statistics and the date when each Min/Max value was first seen. The history of all low-voltage events is available by button click. The display below is updated every 60 seconds by Ajax.
