APCUPSD-UPS(8)
==============

NAME
----

apcupsd-ups - Driver for apcupsd client access

NOTE
----

This man page only documents the specific features of the
*apcupsd-ups* driver.  For information about the core driver, see
linkman: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 has a required UPS access mode missing from NUT.

EXTRA ARGUMENTS
---------------

This driver supports the following optional settings in linkman: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"

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).

|===============================

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 *apcupsd*
exposes the UPS to the network).
