For all other cases use the , which supports multiple jobs, is more efficient and performs calculations on top of the kernel provided values." It will provide charts for all configured system sensors, by reading sensors directly from the kernel. The values graphed are the raw hardware values of the sensors. This collector is only supported on the following platforms: Linux This collector supports collecting metrics from multiple instances of this integration, including remote instances. By default, the collector will try to read entries under `/sys/devices` The default configuration for this integration does not impose any limits on data collection. The default configuration for this integration is not expected to impose a significant performance impact on the system. Metrics grouped by scope. The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels. Metrics related to sensor chips. Each chip provides its own set of the following metrics. This scope has no labels. Metrics: | Metric | Dimensions | Unit | |:|:-|:-| | sensors.temp | {filename} | Celsius | | sensors.volt | {filename} | Volts | | sensors.curr | {filename} | Ampere | | sensors.power | {filename} | Watt | | sensors.fans | {filename} | Rotations / Minute | | sensors.energy | {filename} | Joule | | sensors.humidity | {filename} | Percent | There are no alerts configured by default for this integration. If , make sure `netdata-plugin-chartsd` is installed. The `sensors` collector is disabled by default. To enable it, use `edit-config` from the Netdata , which is typically at `/etc/netdata`, to edit the `charts.d.conf`

```bash cd /etc/netdata # Replace this path with your Netdata config directory, if different sudo ./edit-config charts.d.conf ``` Change the value of the `sensors` setting to `force` and uncomment the line. Save the file and restart the Netdata Agent with `sudo systemctl restart netdata`, or the for your system. The configuration file name for this integration is `charts.d/sensors.conf`. You can edit the configuration file using the `edit-config` script from the Netdata . ```bash cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata sudo ./edit-config charts.d/sensors.conf ``` The config file is sourced by the charts.d plugin. It's a standard bash file. The following collapsed table contains all the options that can be configured for the sensors collector. <details><summary>Config options</summary> | Name | Description | Default | Required | |:-|:--|:-|:--:| | sensorssysdir | The directory the kernel exposes sensor data. | /sys/devices | no | | sensorssysdepth | How deep in the tree to check for sensor data. | 10 | no | | sensorssourceupdate | If set to 1, the script will overwrite internal script functions with code generated ones. | 1 | no | | sensorsupdateevery | The data collection frequency. If unset, will inherit the netdata update frequency. | 1 | no | | sensors_priority | The charts priority on the dashboard. | 90000 | no | | sensors_retries | The number of retries to do in case of failure before disabling the collector. | 10 | no | </details> Set a different sensors path depth ```yaml sensorssysdepth=5 ``` To troubleshoot issues with the `sensors` collector, run the `charts.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]`. ```bash cd /usr/libexec/netdata/plugins.d/ ``` Switch to the `netdata` user. ```bash sudo -u netdata -s ``` Run the `charts.d.plugin` to debug the collector: ```bash ./charts.d.plugin debug 1 sensors ```
