Thermal

The thermal input plugin reports system temperatures periodically -- each second by default. Currently this plugin is only available for Linux.

The following tables 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
Interval_Sec	Polling interval (seconds). default: 1
Interval_NSec	Polling interval (nanoseconds). default: 0
name_regex	Optional name filter regex. default: None
type_regex	Optional type filter regex. default: None

Getting Started

In order to get temperature(s) of your system, you can run the plugin from the command line or through the configuration file:

Command Line

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

Some systems provide multiple thermal zones. In this example monitor only thermal_zone0 by name, once per minute.
