APCUPSD-UPS(8) NUT Manual APCUPSD-UPS(8) NAME apcupsd-ups - Driver for apcupsd client access SYNOPSIS apcupsd-ups -h apcupsd-ups -a UPS_NAME [OPTIONS] Note This man page only documents the specific features of the apcupsd-ups driver. For information about the core driver, see nutupsdrv(8). DESCRIPTION This driver is a client to apcupsd (another UPS monitoring project). apcupsd-ups acts as an apcupsd client, simply forwarding data. This can be useful in cases where both protocols are required in a network, or in case apcupsd code base has a required UPS access mode missing from NUT. EXTRA ARGUMENTS This driver supports the following optional settings in nut.conf(5): port=<hostname>[:<port>] This is the name of a remote host running apcupsd (plus an optional port). For instance: [apcupsd] driver = apcupsd-ups port = localhost desc = "apcupsd client" For IPv6 addresses, use square brackets for the hostname part (so colons in it are not mistaken to be the port, especially if using the default one): [apcupsd] driver = apcupsd-ups port = "[::1]:3551" desc = "apcupsd client" BACKGROUND This driver was originally written in one evening to allow interoperating with apcupsd. SUPPORTED VARIABLES The following variables are translated from apcupsd to NUT. All times should be converted to seconds (please file a bug if you notice a mismatch in units). +------------------+-------------------------+ | apcupsd variable | NUT variable(s) | +------------------+-------------------------+ | | | | BCHARGE | battery.charge | +------------------+-------------------------+ | | | | MBATTCHG | battery.charge.low | +------------------+-------------------------+ | | | | RETPCT | battery.charge.restart | +------------------+-------------------------+ | | | | BATTDATE | battery.date | +------------------+-------------------------+ | | | | TIMELEFT | battery.runtime | +------------------+-------------------------+ | | | | MINTIMEL | battery.runtime.low | +------------------+-------------------------+ | | | | BATTV | battery.voltage | +------------------+-------------------------+ | | | | NOMBATTV | battery.voltage.nominal | +------------------+-------------------------+ | | | | LINEFREQ | input.frequency | +------------------+-------------------------+ | | | | SENSE | input.sensitivity | +------------------+-------------------------+ | | | | HITRANS | input.transfer.high | +------------------+-------------------------+ | | | | LOTRANS | input.transfer.low | +------------------+-------------------------+ | | | | LASTXFER | input.transfer.reason | +------------------+-------------------------+ | | | | LINEV | input.voltage | +------------------+-------------------------+ | | | | MAXLINEV | input.voltage.maximum | +------------------+-------------------------+ | | | | MINLINEV | input.voltage.minimum | +------------------+-------------------------+ | | | | NOMINV | input.voltage.nominal | +------------------+-------------------------+ | | | | LINEFREQ | output.frequency | +------------------+-------------------------+ | | | | OUTPUTV | output.voltage | +------------------+-------------------------+ | | | | NOMOUTV | output.voltage.nominal | +------------------+-------------------------+ | | | | DATE | ups.date, ups.time | +------------------+-------------------------+ | | | | DSHUTD | ups.delay.shutdown | +------------------+-------------------------+ | | | | DWAKE | ups.delay.start | +------------------+-------------------------+ | | | | FIRMWARE | ups.firmware, | | | ups.firmware.aux | +------------------+-------------------------+ | | | | UPSNAME | ups.id | +------------------+-------------------------+ | | | | LOADPCT | ups.load | +------------------+-------------------------+ | | | | MANDATE | ups.mfr.date | +------------------+-------------------------+ | | | | NOMPOWER | ups.realpower.nominal | +------------------+-------------------------+ | | | | SERIALNO | ups.serial | +------------------+-------------------------+ | | | | STATUS | ups.status | +------------------+-------------------------+ | | | | ITEMP | ups.temperature | +------------------+-------------------------+ | | | | STESTI | ups.test.interval | +------------------+-------------------------+ | | | | SELFTEST | ups.test.result | +------------------+-------------------------+ LIMITATIONS Access to apcupsd is strictly read only: no commands can be issued. This stems from the design of apcupsd, where the settings are changed in apctest. In order to run apctest, apcupsd must be stopped (and it is apcupsd that exposes the UPS to the network and to this NUT driver as its client).
