Nut upsuser - May 2009 - upsmon shutdown based on Time since power fail.

For various reasons - I have been trying to get my Desktops and/or 
servers to shut-down a fixed time after a power fail - or better still a 
fixed time - or a low battery whichever comes first.
I note in my upsc:

*> upsc belkinusb*
battery.charge: 100
battery.charge.low: 30
battery.charge.warning: 30
battery.runtime: 120
battery.type: PbAc
battery.voltage: 27.3
battery.voltage.nominal: 24
driver.name: usbhid-ups
driver.parameter.pollinterval: 2
driver.parameter.port: auto
driver.version: 2.2.0-
driver.version.data: Belkin HID 0.1
driver.version.internal: 0.30
input.frequency: 50.0
input.frequency.nominal: 50
input.sensitivity: normal
input.transfer.high: 264
input.transfer.high.max: 269
input.transfer.high.min: 259
input.transfer.low: 187
input.transfer.low.max: 192
input.transfer.low.min: 182
input.voltage: 247.4
input.voltage.nominal: 230
output.frequency: 50.0
output.voltage: 248.4
ups.beeper.status: enabled
ups.delay.restart: 0
ups.delay.shutdown: 0
ups.firmware: 2
ups.load: 52
ups.load.high: 100
ups.mfr: Belkin 
ups.model: UPS
ups.power.nominal: 1200
ups.productid: 0912
ups.serial: 01          
ups.status: OL CHRG
ups.test.result: Done and passed
ups.type: offline
ups.vendorid: 050d

the battery runtime is set to 120 - though the UPS runs much longer than 
120 seconds on battery. I am therefore not sure what this parameter means.

Moreover upsrw shows:

*> upsrw belkinusb*
[input.sensitivity]
Input power sensitivity
Type: STRING
Value: normal

[input.transfer.high]
High voltage transfer point
Type: STRING
Value: 264

[input.transfer.low]
Low voltage transfer point
Type: STRING
Value: 187

[ups.beeper.status]
UPS beeper status
Type: STRING
Value: enabled

Which I think means these are the only parameters I can change in the UPS.

Is there another parameter somewhere - probably in upsmon - which would 
allow me to specify a shut-down after (say) 3 minutes running on battery
regardless of battery status?

One of the reasons for this request is that I have a desktop and a server
running from the same UPS -
and would like to ensure the desktop shuts down (or better still hibernates)
before the server shuts down.

If there is some documentation somewhere covering this question - please feel
free to point me to the documentation.

Regards

Richard.

In the upsmon.conf file you use NOTIFYCMD and ONBATT to execute a  
shutdown $time

Then you use a ONLINE to execute a -c to cancel a shutdown if the  
power returns.

Don't do this. As written in the FAQ, in some cases you may wish/need  
to use 'upssched' to start shutting down your systems before the UPS  
indicates the battery is low. In that case, you probably want to call  
'upsmon -c fsd' instead, which will initiate a shutdown on the upsmon  
master (in your case, your server). This means that you will have to  
configure the upsmon on the server (FINALDELAY) to allow for enough  
time for your clients to shutdown. This will put your master at risk  
in case of repeated power failures however, so don't overdo this.
