Distribution's init script should source this file to see which # component(s) has to be started. # # The values of MODE can be: # - none: NUT is not configured, or use the Integrated Power Management, or use # some external system to startup NUT components. So nothing is to be started. # - standalone: This mode address a local only configuration, with 1 UPS # protecting the local system. This implies to start the 3 NUT layers (driver, # upsd and upsmon) and the matching configuration files. This mode can also # address UPS redundancy. # - netserver: same as for the standalone configuration, but also need # some more network access controls (firewall, tcp-wrappers) and possibly a # specific LISTEN directive in upsd.conf. # Since this MODE is opened to the network, a special care should be applied # to security concerns. # - netclient: this mode only requires upsmon. # # IMPORTANT NOTE: # This file is intended to be sourced by shell scripts. # You MUST NOT use spaces around the equal sign!

| # 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 # it would look something like this: # # MONITOR snoopy@doghouse 1 upsmonuser mypassword master # # It might look like this if monitoring in slave mode: # # MONITOR snoopy@doghouse 1 upsmonuser mypassword slave # # Configuration directives # ------------------------ # # 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. # # 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. # # 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. # # # 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.

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.

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.

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 pager.txt in the docs directory. # # Example: # NOTIFYCMD /usr/local/ups/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 shutdown.txt file in the docs subdirectory for more information.

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.
