nut-recorder - Utility to record device status and values changes

       Arnaud Quette

nut-recorder is an utility to record sequences from running devices (such as power failures, or any other
       value changes) from upsd(8) data server, and dump it in a .seq format.

       The .seq file can then be used by the dummy-ups(8) driver to replay the sequence.

       To record data from ups1@host1 every 10 seconds:

           :; nut-recorder ups1@host1' ups1-output.seq 10
           . . .
           battery.charge: 100.0
           battery.voltage: 13.9
           battery.voltage.nominal: 13.6
           ups.status: OL
           . . .
           battery.charge: 90.0
           ups.status: OB
           . . .

       You can then define a dummy device in ups.conf(5):

           [ups-test]
                   driver = dummy-ups
                   port = ups1-output.seq

device-name
           Record the changes of this device. The format for this option is devname[@hostname[:port]]. The
           default hostname is "localhost".

       output-file
           Optional. Data will be saved to this file. The default is dummy-device.seq.

       interval
           Optional. The status of the device will be checked every interval. The default is 5 seconds.
