# Network UPS Tools: example upsmon configuration
|
|
#
|
|
# This file contains passwords, so keep it secure.
|
|
|
|
# --------------------------------------------------------------------------
|
|
# RUN_AS_USER <userid>
|
|
#
|
|
# By default, upsmon splits into two processes. One stays as root and
|
|
# waits to run the SHUTDOWNCMD. The other one switches to another userid
|
|
# and does everything else.
|
|
#
|
|
# The default nonprivileged user is set at compile-time with
|
|
# 'configure --with-user=...'.
|
|
#
|
|
# You can override it with '-u <user>' when starting upsmon, or just
|
|
# define it here for convenience.
|
|
#
|
|
# Note: if you plan to use the reload feature, this file (upsmon.conf)
|
|
# must be readable by this user! Since it contains passwords, DO NOT
|
|
# make it world-readable. Also, do not make it writable by the upsmon
|
|
# user, since it creates an opportunity for an attack by changing the
|
|
# SHUTDOWNCMD to something malicious.
|
|
#
|
|
# For best results, you should create a new normal user like "nutmon",
|
|
# and make it a member of a "nut" group or similar. Then specify it
|
|
# here and grant read access to the upsmon.conf for that group.
|
|
#
|
|
# This user should not have write access to upsmon.conf.

# MONITOR <system> <powervalue> <username> <password> ("master"|"slave")
|
|
#
|
|
# List systems you want to monitor. Not all of these may supply power
|
|
# to the system running upsmon, but if you want to watch it, it has to
|
|
# be in this section.
|
|
#
|
|
# You must have at least one of these declared.
|
|
#
|
|
# <system> is a UPS identifier in the form <upsname>@<hostname>[:<port>]
|
|
# like ups@localhost, su700@mybox, etc.
|
|
#
|
|
# Examples:
|
|
#
|
|
# - "su700@mybox" means a UPS called "su700" on a system called "mybox"
|
|
#
|
|
# - "fenton@bigbox:5678" is a UPS called "fenton" on a system called
|
|
# "bigbox" which runs upsd on port "5678".
|
|
#
|
|
# The UPS names like "su700" and "fenton" are set in your ups.conf
|
|
# in [brackets] which identify a section for a particular driver.
|
|
#
|
|
# If the ups.conf on host "doghouse" has a section called "snoopy", the
|
|
# identifier for it would be "snoopy@doghouse".
|
|
#
|
|
# <powervalue> is an integer - the number of power supplies that this UPS
|
|
# feeds on this system. Most computers only have one power supply, so this
|
|
# is normally set to 1. You need a pretty big or special box to have any
|
|
# other value here.
|
|
#
|
|
# You can also set this to 0 for a system that doesn't supply any power,
|
|
# but you still want to monitor. Use this when you want to hear about
|
|
# changes for a given UPS without shutting down when it goes critical,
|
|
# unless <powervalue> is 0.
|
|
#
|
|
# <username> and <password> must match an entry in that system's
|
|
# upsd.users. If your username is "monmaster" and your password is
|
|
# "blah", the upsd.users would look like this:
|
|
#
|
|
# [monmaster]
|
|
# password = blah
|
|
# upsmon master (or slave)
|
|
#
|
|
# "master" means this system will shutdown last, allowing the slaves
|
|
# time to shutdown first.
|
|
#
|
|
# "slave" means this system shuts down immediately when power goes critical.
|
|
#
|
|
# Examples:
|
|
#
|
|
# MONITOR myups@bigserver 1 monmaster blah master
|
|
# MONITOR su700@server.example.com 1 upsmon secretpass slave
|
|
# MONITOR myups@localhost 1 upsmon pass master (or slave)

# MINSUPPLIES <num>

# Give the number of power supplies that must be receiving power to keep
|
|
# this system running. Most systems have one power supply, so you would
|
|
# put "1" in this field.
|
|
#
|
|
# Large/expensive server type systems usually have more, and can run with
|
|
# a few missing. The HP NetServer LH4 can run with 2 out of 4, for example,
|
|
# so you'd set that to 2. The idea is to keep the box running as long
|
|
# as possible, right?
|
|
#
|
|
# Obviously you have to put the redundant supplies on different UPS circuits
|

# HOSTSYNC - How long upsmon will wait before giving up on another upsmon
|
|
#
|
|
# The master upsmon process uses this number when waiting for slaves to

|
# disconnect once it has set the forced shutdown (FSD) flag. If they
|
|
# don't disconnect after this many seconds, it goes on without them.
|
|
#
|
|
# Similarly, upsmon slave processes wait up to this interval for the
|
|
# master upsmon to set FSD when a UPS they are monitoring goes critical -
|
|
# that is, on battery and low battery. If the master doesn't do its job,
|
|
# the slaves will shut down anyway to avoid damage to the file systems.
|
|
#
|
|
# This "wait for FSD" is done to avoid races where the status changes
|
|
# to critical and back between polls by the master.

# --------------------------------------------------------------------------
|
|
# DEADTIME - Interval to wait before declaring a stale ups "dead"
|
|
#
|
|
# upsmon requires a UPS to provide status information every few seconds
|
|
# (see POLLFREQ and POLLFREQALERT) to keep things updated. If the status
|
|
# fetch fails, the UPS is marked stale. If it stays stale for more than
|
|
# DEADTIME seconds, the UPS is marked dead.
|
|
#
|
|
# A dead UPS that was last known to be on battery is assumed to have gone
|
|
# to a low battery condition. This may force a shutdown if it is providing
|
|
# a critical amount of power to your system.
|
|
#
|
|
# Note: DEADTIME should be a multiple of POLLFREQ and POLLFREQALERT.
|
|
# Otherwise you'll have "dead" UPSes simply because upsmon isn't polling
|
|
# them quickly enough. Rule of thumb: take the larger of the two
|
|
# POLLFREQ values, and multiply by 3.
