Linux Sensors (lm-sensors)

Plugin: python.d.plugin Module: sensors


Examine Linux Sensors metrics with Netdata for insights into hardware health and performance.

Enhance your system’s reliability with real-time hardware health insights.

Reads system sensors information (temperature, voltage, electric current, power, etc.) via lm-sensors.

This collector is supported on all platforms.

This collector supports collecting metrics from multiple instances of this integration, including remote instances.

Default Behavior


The following type of sensors are auto-detected:

  • temperature - fan - voltage - current - power - energy - humidity


The default configuration for this integration does not impose any limits on data collection.

Performance Impact

The default configuration for this integration is not expected to impose a significant performance impact on the system.



No action required.



The configuration file name for this integration is python.d/sensors.conf.

You can edit the configuration file using the edit-config script from the Netdata config directory.

cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config python.d/sensors.conf


There are 2 sections:

  • Global variables
  • One or more JOBS that can define multiple different instances to monitor.

The following options can be defined globally: priority, penalty, autodetection_retry, update_every, but can also be defined per JOB to override the global values.

Additionally, the following collapsed table contains all the options that can be configured inside a JOB definition.

Every configuration JOB starts with a job_name value which will appear in the dashboard, unless a name parameter is specified.

Name Description Default Required
types The types of sensors to collect. temperature, fan, voltage, current, power, energy, humidity True
update_every Sets the default data collection frequency. 1 False
priority Controls the order of charts at the netdata dashboard. 60000 False
autodetection_retry Sets the job re-check interval in seconds. 0 False
penalty Indicates whether to apply penalty to update_every in case of failures. yes False



Default configuration.

  - temperature
  - fan
  - voltage
  - current
  - power
  - energy
  - humidity


Metrics grouped by scope.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.

Per chip

Metrics related to chips. Each chip provides a set of the following metrics, each having the chip name in the metric name as reported by sensors -u.

This scope has no labels.


Metric Dimensions Unit
sensors.temperature a dimension per sensor Celsius
sensors.voltage a dimension per sensor Volts
sensors.current a dimension per sensor Ampere
sensors.power a dimension per sensor Watt a dimension per sensor Rotations/min a dimension per sensor Joule
sensors.humidity a dimension per sensor Percent


There are no alerts configured by default for this integration.


Debug Mode

To troubleshoot issues with the sensors collector, run the python.d.plugin with the debug option enabled. The output should give you clues as to why the collector isn’t working.

  • Navigate to the plugins.d directory, usually at /usr/libexec/netdata/plugins.d/. If that’s not the case on your system, open netdata.conf and look for the plugins setting under [directories].

    cd /usr/libexec/netdata/plugins.d/
  • Switch to the netdata user.

    sudo -u netdata -s
  • Run the python.d.plugin to debug the collector:

    ./python.d.plugin sensors debug trace

lm-sensors doesn’t work on your device

ACPI ring buffer errors are printed
