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

nut-recorder device-name [output-file] [interval]

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

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

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.

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
