[Nut-upsuser] Do I need to configure times and percents?

In the default configuration, NUT's upsmon program shuts the system down after the UPS reports a low battery. Your UPS may or may not allow that threshold to be configured, so there are several other options if you want to shut down after a specific time on battery, or when other conditions are reached. >> ?My UPS is Advice PRS850. > > You may want to check the list archives to see if anyone else has additional information on other UPS models from this manufacturer: > > ???http://www.networkupstools.org/support.html#_mailing_lists > > It actually isn't on our hardware compatibility list: > > ???http://buildbot.networkupstools.org/~buildbot/cayman/docs/latest/stable-hcl.html > > If you post additional details (output of upsc and upsrw) someone may be able to offer more specific suggestions.$ upsc advice Init SSL without certificate database battery.charge: 100 battery.voltage: 13.70 battery.voltage.high: 13.00 battery.voltage.low: 10.40 battery.voltage.nominal: 12.0 device.type: ups driver.name: blazer_usb driver.parameter.pollinterval: 2 driver.parameter.port: /dev/ttyS0 driver.parameter.productid: 5161 driver.parameter.vendorid: 0665 driver.version: 2.7.2 driver.version.internal: 0.11 input.current.nominal: 3.0 input.frequency: 50.0 input.frequency.nominal: 50 input.voltage: 234.9 input.voltage.fault: 234.9 input.voltage.nominal: 230 output.voltage: 234.9 ups.beeper.status: enabled ups.delay.shutdown: 30 ups.delay.start: 180 ups.load: 18 ups.productid: 5161 ups.status: OL ups.type: offline / line interactive ups.vendorid: 0665 -- Victor Porton - http://portonvictor.org

Also, if battery.charge works, you can use "ignorelb" if you want to shut down at another level of charge: http://www.networkupstools.org/docs/man/ups.conf.html#_ups_fields> ups.delay.shutdown: 30 > ups.delay.start: 180These timers are in seconds. You will want to verify this, but according to those values, the UPS will shut off its output 30 seconds after the shutdown signal (so you need to make sure that your OS shutdown takes less time than that). Does "upsrw -l advice" show anything? -- Charles Lepple clepple at gmail
