Linux machine sensors collector

Use this collector when lm-sensors doesn't work on your device (e.g. for RPi temperatures). For all other cases use the Python collector, which supports multiple jobs, is more efficient and performs calculations on top of the kernel provided values.

This plugin 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.

The plugin will create Netdata charts for:

  1. Temperature
  2. Voltage
  3. Current
  4. Power
  5. Fans Speed
  6. Energy
  7. Humidity

One chart for every sensor chip found and each of the above will be created.

Enable the collector​

The sensors collector is disabled by default. To enable it, edit the charts.d.conf file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata   # Replace this path with your Netdata config directory, if different
sudo ./edit-config charts.d.conf

It also needs to be set to "force" to be enabled:

# example=force
sensors=force

Configuration​

Edit the charts.d/sensors.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata   # Replace this path with your Netdata config directory, if different
sudo ./edit-config charts.d/sensors.conf

This is the internal default for charts.d/sensors.conf

# the directory the kernel keeps sensor data
sensors_sys_dir="${NETDATA_HOST_PREFIX}/sys/devices"

# how deep in the tree to check for sensor data
sensors_sys_depth=10

# if set to 1, the script will overwrite internal
# script functions with code generated ones
# leave to 1, is faster
sensors_source_update=1

# how frequently to collect sensor data
# the default is to collect it at every iteration of charts.d
sensors_update_every=

# array of sensors which are excluded
# the default is to include all
sensors_excluded=()
