## 3. 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
    -o, --once            log one line, then exit
    -w WAIT, --wait WAIT  wait WAIT seconds after each log line, default 60
    -v, --verbose         be verbose
    -V, --version         show program's version number and exit

## 4. 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.

## 5. 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

## 6. 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.
