Thermal

The Thermal input plugin reports system temperatures. This plugin is available only for Linux.

The following table describes the information generated by the plugin:

Key	Description
name	The name of the thermal zone, such as thermal_zone0.
type	The type of the thermal zone, such as x86_pkg_temp.
temp	Current temperature in Celsius.

Configuration parameters

The plugin supports the following configuration parameters:

Key	Description	Default
Interval_Sec	Polling interval (seconds).	1
Interval_NSec	Polling interval (nanoseconds).	0
name_regex	Optional name filter regular expression.	none
type_regex	Optional type filter regular expression.	none
Threaded	Indicates whether to run this input in its own thread.	false.

Get started

To get the temperature of your system, you can run the plugin from the command line or through the configuration file.

Command line

Run Fluent Bit from the command line with the following command:

fluent-bit -i thermal -t my_thermal -o stdout -m '*'

You should see output similar to the following:

...
[0] my_thermal: [1566099584.000085820, {"name"=>"thermal_zone0", "type"=>"x86_pkg_temp", "temp"=>60.000000}]
[1] my_thermal: [1566099585.000136466, {"name"=>"thermal_zone0", "type"=>"x86_pkg_temp", "temp"=>59.000000}]
[2] my_thermal: [1566099586.000083156, {"name"=>"thermal_zone0", "type"=>"x86_pkg_temp", "temp"=>59.000000}]
...

Some systems provide multiple thermal zones. This example monitors only thermal_zone0 by name, once per minute:

fluent-bit -i thermal -t my_thermal -p "interval_sec=60" -p "name_regex=thermal_zone0" -o stdout -m '*'

Which returns output similar to:

...
[0] my_temp: [1565759542.001053749, {"name"=>"thermal_zone0", "type"=>"pch_skylake", "temp"=>48.500000}]
[0] my_temp: [1565759602.001661061, {"name"=>"thermal_zone0", "type"=>"pch_skylake", "temp"=>48.500000}]
...

Configuration file

In your main configuration file append the following:

fluent-bit.yaml

pipeline:
  inputs:
    - name: thermal
      tag: my_thermal

  outputs:
    - name: stdout
      match: '*'
