.SH "NAME"
nut-recorder \- utility to record device status and values changes
.SH "SYNOPSIS"
.sp
\fBnut\-recorder\fR \fIdevice\-name\fR [output\-file] [interval]
.SH "DESCRIPTION"
.sp
\fBnut\-recorder\fR 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\&.
.sp
The \&.seq file can then be used by the \fBdummy-ups\fR(8) driver to replay the sequence\&.
.SH "OPTIONS"
.PP
\fIdevice\-name\fR
.RS 4
Record the changes of this device\&. The format for this option is
\fIdevname[@hostname[:port]]\fR\&. The default hostname is "localhost"\&.
.RE
.PP
\fIoutput\-file\fR
.RS 4
Optional\&. Data will be saved to this file\&. The default is
\fIdummy\-device\&.seq\fR\&.
.RE
.PP
\fIinterval\fR
.RS 4
Optional\&. The status of the device will be checked every
\fIinterval\fR\&. The default is 5 seconds\&.
.RE
.SH "EXAMPLES"
.sp
To record data from \fIups1@host1\fR every 10 seconds:
.sp
.if n \{\
.RS 4
.\}
.nf
$ nut\-recorder ups1@host1\*(Aq 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
\&. \&. \&.
.fi
.if n \{\
.RE
.\}
.sp
You can then define a dummy device in \fBups.conf\fR(5):
.sp
.if n \{\
.RS 4
.\}
.nf
[ups\-test]
        driver = dummy\-ups
        port = ups1\-output\&.seq
.fi
.if n \{\
.RE
.\}
