Linux Sensors
Plugin: go.d.plugin Module: sensors
Overview
This collector gathers real-time system sensor statistics using the sysfs interface.
Supported sensors:
- Temperature
- Voltage
- Fan
- Current
- Power
- Energy
- Humidity
- Intrusion
This collector is supported on all platforms.
This collector only supports collecting metrics from a single instance of this integration.
Default Behavior
Auto-Detection
Automatically discovers and exposes all available sensors on the system through the sysfs interface.
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.
Setup
Prerequisites
No action required.
Configuration
File
The configuration file name for this integration is go.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 go.d/sensors.conf
Options
The following options can be defined globally: update_every.
| Name | Description | Default | Required |
|---|---|---|---|
| update_every | Data collection frequency. | 10 | no |
| relabel | A list used to update existing sensor labels or add labels to sensors that don’t have them. | [] | no |
| relabel[].chip | Pattern to match the chip_id label value. |
no | |
| relabel[].sensors | A list of sensors to be relabeled for the specified chip. | [] | no |
| relabel[].sensors[].name | The exact sensor name (e.g., 'temp1', 'in1', 'voltage1'). |
no | |
| relabel[].sensors[].label | The new label value for the sensor. | no |
Examples
Custom update_every
Allows you to override the default data collection interval.
jobs:
- name: sensors
update_every: 5 # Collect sensors statistics every 5 seconds
Renaming labels
Allows you to override/add labels.
jobs:
- name: sensors
relabel:
- chip: as99127f-*
sensors:
- name: temp1
label: Mobo Temp
- name: temp2
label: CPU0 Temp
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 sensor
These metrics refer to the system sensor.
Labels:
| Label | Description |
|---|---|
| chip | The path to the sensor’s chip device, excluding the /sys/devices prefix. This provides a unique identifier for the physical hardware component. |
| chip_id | A unique identifier for the sensor’s chip, formatted as chipName-busType-hash. |
| sensor | The name of the specific sensor within the chip device. This provides a direct identifier for the individual measurement point. |
| label | A label provided by the kernel driver to indicate the intended use or purpose of the sensor. |
Metrics:
| Metric | Dimensions | Unit |
|---|---|---|
| sensors.chip_sensor_temperature | input | Celsius |
| sensors.chip_sensor_temperature_alarm | clear, triggered | status |
| sensors.chip_sensor_voltage | input | Volts |
| sensors.chip_sensor_voltage_average | average | Volts |
| sensors.chip_sensor_voltage_alarm | clear, triggered | status |
| sensors.chip_sensor_fan | input | RPM |
| sensors.chip_sensor_fan_alarm | clear, triggered | status |
| sensors.chip_sensor_current | input | Amperes |
| sensors.chip_sensor_current_average | average | Amperes |
| sensors.chip_sensor_current_alarm | clear, triggered | status |
| sensors.chip_sensor_power | input | Watts |
| sensors.chip_sensor_power_average | average | Watts |
| sensors.chip_sensor_power_alarm | clear, triggered | status |
| sensors.chip_sensor_energy | input | Joules |
| sensors.chip_sensor_humidity | input | percent |
| sensors.chip_sensor_intrusion_alarm | clear, triggered | status |
Alerts
There are no alerts configured by default for this integration.
Troubleshooting
Debug Mode
Important: Debug mode is not supported for data collection jobs created via the UI using the Dyncfg feature.
To troubleshoot issues with the sensors collector, run the go.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.ddirectory, usually at/usr/libexec/netdata/plugins.d/. If that’s not the case on your system, opennetdata.confand look for thepluginssetting under[directories].cd /usr/libexec/netdata/plugins.d/ -
Switch to the
netdatauser.sudo -u netdata -s -
Run the
go.d.pluginto debug the collector:./go.d.plugin -d -m sensors
Getting Logs
If you’re encountering problems with the sensors collector, follow these steps to retrieve logs and identify potential issues:
- Run the command specific to your system (systemd, non-systemd, or Docker container).
- Examine the output for any warnings or error messages that might indicate issues. These messages should provide clues about the root cause of the problem.
System with systemd
Use the following command to view logs generated since the last Netdata service restart:
journalctl _SYSTEMD_INVOCATION_ID="$(systemctl show --value --property=InvocationID netdata)" --namespace=netdata --grep sensors
System without systemd
Locate the collector log file, typically at /var/log/netdata/collector.log, and use grep to filter for collector’s name:
grep sensors /var/log/netdata/collector.log
Note: This method shows logs from all restarts. Focus on the latest entries for troubleshooting current issues.
Docker Container
If your Netdata runs in a Docker container named “netdata” (replace if different), use this command:
docker logs netdata 2>&1 | grep sensors
