# Network UPS Tools: example ups.conf
#
# --- SECURITY NOTE ---
#
# If you use snmp-ups and set a community string in here, you
# will have to secure this file to keep other users from obtaining
# that string. It needs to be readable by upsdrvctl and any drivers,
# and by upsd.
#
# ---
#
# This is where you configure all the UPSes that this system will be
# monitoring directly. These are usually attached to serial ports, but
# USB devices and SNMP devices are also supported.
#
# This file is used by upsdrvctl to start and stop your driver(s), and
# is also used by upsd to determine which drivers to monitor. The
# drivers themselves also read this file for configuration directives.
#
# The general form is:
#
# [upsname]
# driver = <drivername>
# port = <portname>
# < any other directives here >
#
# The section header ([upsname]) can be just about anything as long as
# it is a single word inside brackets. upsd uses this to uniquely
# identify a UPS on this system.
#
# If you have a UPS called snoopy, your section header would be "[snoopy]".
# On a system called "doghouse", the line in your upsmon.conf to monitor
# and manage it would look something like this:
#
# MONITOR snoopy@doghouse 1 upsmonuser mypassword primary
#
# It might look like this if monitoring in "secondary" mode (without any
# ability to directly manage the UPS) from a different system:
#
# MONITOR snoopy@doghouse 1 upsmonuser mypassword secondary
#
# Configuration directives
# ------------------------
#
# These directives are used by upsdrvctl only and should be specified outside
# of a driver definition:
#
# maxretry: OPTIONAL. Specify the number of attempts to start the driver(s),
# in case of failure, before giving up. A delay of 'retrydelay' is
# inserted between each attempt. Caution should be taken when using
# this option, since it can impact the time taken by your system to
# start.
#
# The built-in default is 1 attempt.
#
# retrydelay: OPTIONAL. Specify the delay between each restart attempt of the
# driver(s), as specified by 'maxretry'. Caution should be taken
# when using this option, since it can impact the time taken by your
# system to start.
#
# The default is 5 seconds.
#
# chroot: OPTIONAL. Used for securing. See man page for details.
#
# driverpath: OPTIONAL. Used for custom setups. See man page for details.
#
# nowait: OPTIONAL. Tell upsdrvctl to not wait at all for the driver(s)
# to execute the requested command. Fire and forget.
#
# pollinterval: OPTIONAL. The status of the UPS will be refreshed after a
# maximum delay which is controlled by this setting (default
# 2 seconds). This may be useful if the driver is creating too
# much of a load on your system or network.
# Note that some drivers also have an option called *pollfreq*
# which controls how frequently some of the less critical
# parameters are polled. See respective driver man pages.
#
# Set maxretry to 3 by default, this should mitigate race with slow devices:
maxretry = 3
# These directives can be set outside and inside a driver definition, with
# slightly different meanings per context:
#
# maxstartdelay: OPTIONAL. This can be set as a global variable
# above your first UPS definition and it can also be
# set in a UPS section. This value controls how long
# upsdrvctl will wait for the driver to finish starting.
# This keeps your system from getting stuck due to a
# broken driver or UPS.
# The default is 45 seconds.
#
# debug_min: OPTIONAL. Specify a minimum debug level for all driver daemons
# (when specified at global level), or for this driver daemon
# (when specified in a driver section), e.g. for troubleshooting
# a deployment. This does not directly impact the foreground or
# background running mode. If both the global and driver level
# `debug_min` are set, the driver-level setting takes precedence.
# Command-line option `-D` can only increase this verbosity level.
#
# user, group: OPTIONAL. Overrides the compiled-in (also global-section,
# when used in driver section) default unprivileged user/group
# name for NUT device driver. Impacts access rights used for
# the socket file access (group) and communication ports (user).
#
# synchronous: OPTIONAL. The driver work by default in asynchronous
# mode (like *no*) with fallback to synchronous if sending
# fails (i.e *synchronous=auto*). This means that all data
# are pushed by the driver on the communication socket to
# upsd (Unix socket on Unix, Named pipe on Windows) without
# waiting for these data to be actually consumed. With
# some HW, such as ePDUs, that can produce a lot of data,
# asynchronous mode may cause some congestion, resulting in
# the socket to be full, and the driver to appear as not
# connected. By enabling the 'synchronous' flag
# (value = 'yes'), the driver will wait for data to be
# consumed by upsd, prior to publishing more. This can be
# enabled either globally or per driver.
#
# The default is 'no' (i.e. asynchronous mode) for backward
# compatibility of the driver behavior.
#
# These directives are common to all drivers that support ups.conf:
#
# driver: REQUIRED. Specify the program to run to talk to this UPS.
# apcsmart, bestups, and sec are some examples.
#
# port: REQUIRED. The serial port where your UPS is connected.
# /dev/ttyS0 is usually the first port on Linux boxes, for example.
#
# sdorder: OPTIONAL. When you have multiple UPSes on your system, you
# usually need to turn them off in a certain order. upsdrvctl
# shuts down all the 0s, then the 1s, 2s, and so on. To exclude
# a UPS from the shutdown sequence, set this to -1.
#
# The default value for this parameter is 0.
#
# desc: optional, to keep a note of the UPS purpose, location, etc.
#
# nolock: optional, and not recommended for use in this file.
#
# If you put nolock in here, the driver will not lock the
# serial port every time it starts. This may allow other
# processes to seize the port if you start more than one by
# mistake.
#
# This is only intended to be used on systems where locking
# absolutely must be disabled for the software to work.
#
# ignorelb: OPTIONAL. Ignore low battery condition reported by device,
# and evaluate remaining battery charge or runtime instead.
# See man page for details.
#
# usb_set_altinterface(=num): OPTIONAL. Require that NUT calls this method
# to set the interface, even if 0 (default). Some devices require
# the call to initialize; others however can get stuck due to it -
# so it is not called by default. Yet others can be composite
# devices which use a non-zero interface to represent the UPS.
#
# default.<variable>: OPTIONAL. Set a default value for <variable> which is
# used in case the UPS doesn't provide a value, but which will be
# overwritten if a value is available from the UPS, e.g.:
# default.input.voltage.nominal = 230
# will report the nominal input voltage to be 230, unless the UPS
# eventually tells us differently.
#
# override.<variable>: OPTIONAL. Set a value for <value> that overrides
# (for NUT) any value that may be read from the UPS.
# Used for overriding values from the UPS that are clearly wrong
# (e.g. some devices report wrong values for battery voltage):
# override.battery.voltage.nominal = 12
# Use with caution! This will only change the appearance of the
# variable to the outside world (and NUT calculations), internally
# in the UPS the original value is used.
#
# Anything else is passed through to the hardware-specific part of
# the driver.
#
# Examples
# --------
#
# A simple example for a UPS called "powerpal" that uses the blazer_ser
# driver on /dev/ttyS0 is:
#
# [powerpal]
# driver = blazer_ser
# port = /dev/ttyS0
# desc = "Web server"
#
# If your UPS driver requires additional settings, you can specify them
# here. For example, if it supports a setting of "1234" for the
# variable "cable", it would look like this:
#
# [myups]
# driver = mydriver
# port = /dev/ttyS1
# cable = 1234
# desc = "Something descriptive"
#
# To find out if your driver supports any extra settings, start it with
# the -h option and/or read the driver's documentation.
