## SYNOPSIS

```
ntplogtemp [-h] [-l LOGFILE] [-o] [-w WAIT] [-v] [-V]
```

```
-h, --help            show this help message and exit
-l LOGFILE, --logfile LOGFILE
                      append log data to LOGFILE instead of stdout
-q, --quiet                                be quiet

## DESCRIPTION

ntplogtemp gathers temperature readings across a system. The standard user is ntpuser and should have permissions to execute lm\_sensors and smartctl.

The default is to write the data to stdout once every 60 seconds. The log file looks like:

```
# time, sensor, value
1485816568 ZONE0 39.0
1485816568 ZONE1 20.0
1485816568 ZONE2 42.0
1485816568 ZONE3 0.0
```

`Time` is the POSIX time of when the log line is written.

`Sensor` is the sensor the temperature reading was obtained from.

`Value` is the temperature reading in celsius.

## OPTIONS

- `-h, --help`

  Displays usage information and exits.

- `-l LOGFILE, --logfile LOGFILE`

  Append log data to LOGFILE instead of stdout

- `-q, --quiet`

  Quiet output, will not display errors

- `-o, --once`

  Log the data once, then exit

- `-v, --verbose`

  Be verbose

- `-w WAIT, --wait WAIT`

  Wait WAIT seconds after each log line.  The default is 60 seconds.  The minimum wait time is 5 seconds.

- `-V, --version`

  show program’s version number and exit

## USAGE

`ntplogtemp`

This the simplest use of this program. It can be used to check the temperature readings of Zones, CPU, and disk drives every minute.

`ntplogtemp -l /var/log/ntpstats/temperature -w 60 &`

This will continuously log the temperature data in the background to the file /var/log/ntpstats/temperature.  Only log every 60 seconds.
