# Linux Sensors (lm-sensors)
Plugin: python.d.plugin
Module: sensors
## Overview
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](https://hwmon.wiki.kernel.org/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
#### Auto-Detection
The following type of sensors are auto-detected:
- temperature - fan - voltage - current - power - energy - humidity
#### Limits
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.
## Metrics
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.
Metrics:
| 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 |
| sensors.fan | a dimension per sensor | Rotations/min |
| sensors.energy | a dimension per sensor | Joule |
| sensors.humidity | a dimension per sensor | Percent |
## Alerts
There are no alerts configured by default for this integration.
## Setup
### Prerequisites
No action required.
### Configuration
#### File
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](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md#the-netdata-config-directory).
```bash
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config python.d/sensors.conf
```
#### Options
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.
Config options
| 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 |
