# 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.
#
# RUN_AS_USER _ups

# --------------------------------------------------------------------------
# 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
# for this to make sense!  See big-servers.txt in the docs subdirectory
# for more information and ideas on how to use this feature.

MINSUPPLIES 1

# --------------------------------------------------------------------------
# SHUTDOWNCMD "<command>"
#
# upsmon runs this command when the system needs to be brought down.
#
# This should work just about everywhere ... if it doesn't, well, change it.

SHUTDOWNCMD "/sbin/shutdown -hp +0"

# --------------------------------------------------------------------------
# NOTIFYCMD <command>
#
# upsmon calls this to send messages when things happen
#
# This command is called with the full text of the message as one argument.
# The environment string NOTIFYTYPE will contain the type string of
# whatever caused this event to happen.
#
# Note that this is only called for NOTIFY events that have EXEC set with
# NOTIFYFLAG.  See NOTIFYFLAG below for more details.
#
# Making this some sort of shell script might not be a bad idea.  For more
# information and ideas, see docs/scheduling.txt
#
# Example:
# NOTIFYCMD /usr/local/bin/notifyme

# --------------------------------------------------------------------------
# POLLFREQ <n> 
#
# Polling frequency for normal activities, measured in seconds.
#
# Adjust this to keep upsmon from flooding your network, but don't make 
# it too high or it may miss certain short-lived power events.

POLLFREQ 5

# --------------------------------------------------------------------------
# POLLFREQALERT <n>
#
# Polling frequency in seconds while UPS on battery.
#
# You can make this number lower than POLLFREQ, which will make updates
# faster when any UPS is running on battery.  This is a good way to tune 
# network load if you have a lot of these things running.  
#
# The default is 5 seconds for both this and POLLFREQ.

POLLFREQALERT 5

# --------------------------------------------------------------------------
# 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.

HOSTSYNC 15

# --------------------------------------------------------------------------
# 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.

DEADTIME 15

# --------------------------------------------------------------------------
# POWERDOWNFLAG - Flag file for forcing UPS shutdown on the master system
#
# upsmon will create a file with this name in master mode when it's time
# to shut down the load.  You should check for this file's existence in
# your shutdown scripts and run 'upsdrvctl shutdown' if it exists.
#
# See the config-notes.txt file in the docs subdirectory for more information.
# Refer to the section:
# [[UPS_shutdown]] "Configuring automatic shutdowns for low battery events"
# or refer to the online version.

POWERDOWNFLAG /etc/killpower

# --------------------------------------------------------------------------
# NOTIFYMSG - change messages sent by upsmon when certain events occur
#
# You can change the default messages to something else if you like.
#
# NOTIFYMSG <notify type> "message"
#
# NOTIFYMSG ONLINE	"UPS %s on line power"
# NOTIFYMSG ONBATT	"UPS %s on battery"
# NOTIFYMSG LOWBATT	"UPS %s battery is low"
# NOTIFYMSG FSD		"UPS %s: forced shutdown in progress"
# NOTIFYMSG COMMOK	"Communications with UPS %s established"
# NOTIFYMSG COMMBAD	"Communications with UPS %s lost"
# NOTIFYMSG SHUTDOWN	"Auto logout and shutdown proceeding"
# NOTIFYMSG REPLBATT	"UPS %s battery needs to be replaced"
# NOTIFYMSG NOCOMM	"UPS %s is unavailable"
# NOTIFYMSG NOPARENT	"upsmon parent process died - shutdown impossible"
#
# Note that %s is replaced with the identifier of the UPS in question.
#
# Possible values for <notify type>:
#
# ONLINE   : UPS is back online
# ONBATT   : UPS is on battery
# LOWBATT  : UPS has a low battery (if also on battery, it's "critical")
# FSD      : UPS is being shutdown by the master (FSD = "Forced Shutdown")
# COMMOK   : Communications established with the UPS
# COMMBAD  : Communications lost to the UPS
# SHUTDOWN : The system is being shutdown
# REPLBATT : The UPS battery is bad and needs to be replaced
# NOCOMM   : A UPS is unavailable (can't be contacted for monitoring)
# NOPARENT : The process that shuts down the system has died (shutdown impossible)

# --------------------------------------------------------------------------
# NOTIFYFLAG - change behavior of upsmon when NOTIFY events occur
#
# By default, upsmon sends walls (global messages to all logged in users)
# and writes to the syslog when things happen.  You can change this.
#
# NOTIFYFLAG <notify type> <flag>[+<flag>][+<flag>] ...
#
# NOTIFYFLAG ONLINE	SYSLOG+WALL
# NOTIFYFLAG ONBATT	SYSLOG+WALL
# NOTIFYFLAG LOWBATT	SYSLOG+WALL
# NOTIFYFLAG FSD	SYSLOG+WALL
# NOTIFYFLAG COMMOK	SYSLOG+WALL
# NOTIFYFLAG COMMBAD	SYSLOG+WALL
# NOTIFYFLAG SHUTDOWN	SYSLOG+WALL
# NOTIFYFLAG REPLBATT	SYSLOG+WALL
# NOTIFYFLAG NOCOMM	SYSLOG+WALL
# NOTIFYFLAG NOPARENT	SYSLOG+WALL
#
# Possible values for the flags:
#
# SYSLOG - Write the message in the syslog 
# WALL   - Write the message to all users on the system
# EXEC   - Execute NOTIFYCMD (see above) with the message
# IGNORE - Don't do anything
#
# If you use IGNORE, don't use any other flags on the same line.

# --------------------------------------------------------------------------
# RBWARNTIME - replace battery warning time in seconds
#
# upsmon will normally warn you about a battery that needs to be replaced
# every 43200 seconds, which is 12 hours.  It does this by triggering a
# NOTIFY_REPLBATT which is then handled by the usual notify structure
# you've defined above.
# 
# If this number is not to your liking, override it here.

RBWARNTIME 43200

# --------------------------------------------------------------------------
# NOCOMMWARNTIME - no communications warning time in seconds
#
# upsmon will let you know through the usual notify system if it can't
# talk to any of the UPS entries that are defined in this file.  It will
# trigger a NOTIFY_NOCOMM by default every 300 seconds unless you 
# change the interval with this directive.

NOCOMMWARNTIME 300

# --------------------------------------------------------------------------
# FINALDELAY - last sleep interval before shutting down the system
#
# On a master, upsmon will wait this long after sending the NOTIFY_SHUTDOWN
# before executing your SHUTDOWNCMD.  If you need to do something in between
# those events, increase this number.  Remember, at this point your UPS is 
# almost depleted, so don't make this too high.
#
# Alternatively, you can set this very low so you don't wait around when
# it's time to shut down.  Some UPSes don't give much warning for low
# battery and will require a value of 0 here for a safe shutdown.
#
# Note: If FINALDELAY on the slave is greater than HOSTSYNC on the master,
# the master will give up waiting for the slave to disconnect.

FINALDELAY 5

# CERTPATH - path to certificates (database directory or directory with CA's)
#
# When compiled with SSL support, you can enter the certificate path here.
#
# With NSS:
# Certificates are stored in a dedicated database (splitted in 3 files).
# Specify the path of the database directory.
# 
# CERTPATH /etc/nut/cert/upsmon
#
# With OpenSSL:
# Directory containing CA certificates in PEM format, used to verify
# the server certificate presented by the upsd server. The files each
# contain one CA certificate. The files are looked up by the CA subject
# name hash value, which must hence be available.
#
# CERTPATH /usr/ssl/certs
# 
# See 'docs/security.txt' or the Security chapter of NUT user manual
# for more information on the SSL support in NUT.

# --------------------------------------------------------------------------
# CERTIDENT - self certificate name and database password
# CERTIDENT <certificate name> <database password>
#
# When compiled with SSL support with NSS, you can specify the certificate
# name to retrieve from database to authenticate itself and the password
# required to access certificate related private key.
#
# CERTIDENT "my nut monitor" "MyPasSw0rD"
# 
# See 'docs/security.txt' or the Security chapter of NUT user manual
# for more information on the SSL support in NUT.

# --------------------------------------------------------------------------
# CERTHOST - security properties for an host
# CERTHOST <hostname> <certificate name> <certverify> <forcessl>
#
# When compiled with SSL support with NSS, you can specify security directive
# for each server you can contact.
# Each entry maps server name with the expected certificate name and flags
# indicating if the server certificate is verified and if the connection
# must be secure.
#
# CERTHOST localhost "My nut server" 1 1
#
# See 'docs/security.txt' or the Security chapter of NUT user manual
# for more information on the SSL support in NUT.

# --------------------------------------------------------------------------
# CERTVERIFY - make upsmon verify all connections with certificates
# CERTVERIFY 1
#
# When compiled with SSL support, make upsmon verify all connections with 
# certificates.
# Without this, there is no guarantee that the upsd is the right host.
# Enabling this greatly reduces the risk of man in the middle attacks.
# This effectively forces the use of SSL, so don't use this unless
# all of your upsd hosts are ready for SSL and have their certificates
# in order.
# When compiled with NSS support of SSL, can be overriden for host 
# specified with a CERTHOST directive.


# --------------------------------------------------------------------------
# FORCESSL - force upsmon to use SSL
# FORCESSL 1
#
# When compiled with SSL, specify that a secured connection must be used
# to communicate with upsd.
# If you don't use 'CERTVERIFY 1', then this will at least make sure
# that nobody can sniff your sessions without a large effort.  Setting
# this will make upsmon drop connections if the remote upsd doesn't
# support SSL, so don't use it unless all of them have it running.
# When compiled with NSS support of SSL, can be overriden for host 
# specified with a CERTHOST directive.
