Hi everyone,  
i was used to use either

`upower -i /org/freedesktop/UPower/devices/battery_BAT0`

or (when AC is connected)

`path="/sys/class/power_supply/BAT0"; value=$(echo "scale=1; $(cat ${path}/current_now) * $(cat ${path}/voltage_now) / 10^12" | bc); [[$value == "0"]] && echo "" || echo "${value}W"`

to see my laptop power consumption till i have find this amazing netdata tool.  
Unfortunately my “Sensors” tab is only reporting voltages while my “Power Supply” tab is only showing current charge %.  
Is there a way to have access to the actual Watts or Wh?  
I’m using docker with the latest container.

Regards,

You should enable the charts you need in Netdata [configuration](https://learn.netdata.cloud/docs/agent/collectors/proc.plugin#configuration-5)

```auto
[plugin:proc:/sys/class/power_supply]
	battery energy = yes

```

So if i make a copy of the conf from e.g. [http://localhost:19999/netdata.conf](http://localhost:19999/netdata.conf) and paste it with that command enabled in “./netdataconfig/” then according to docker command `-v ./netdataconfig:/etc/netdata` i should be good to go?  
Also is there a way to make a Gauge with such value in the “Overview of the key system metrics.”

EDIT:  
It seems that if i use ./netdataconfig:/etc/netdata:ro (e.g. local folder in order to copy/paste the new conf) as suggested for docker-compose, the tab “Sensor” disappears. I might open an issue on github soon

That’s the guide i’ve followed but without luck, the “Sensor” tab is disappearing without even touching the config itself. I might look into it tomorrow but i’ve double checked going back to default volumes and “Sensor” tab came back again

Well, that indicates that there is a problem, lets check logs

> docker logs NAME 2\>&1 | grep -E -i “sensor|charts.d”

```

But i have noticed that after few minutes the “Sensors” tab appears again (i retyped the command but the result has been the same)

i have added in the config the command above and by browsing it via URL i see the following

```
# section 'plugin:proc:/sys/class/power_supply' is not used.
[plugin:proc:/sys/class/power_supply]
	battery energy = yes

```

Moreover i’ve noticed that if the AC is connected (e.g. battery charging) i can see the current (not the energy) and when there is only BAT0 i can see only the voltage (i can always see the temperature otherwise)

It is as such (with # in front)

`# /sys/class/power_supply = yes`

am i wrong in thinking that the default behavior is “yes” when it is written a such?

Anyway i’ve changed it and now the config is shown as such

```
[plugin:proc:/sys/class/power_supply]
	battery energy = yes
	# battery capacity = yes
	# battery charge = no
	# power supply voltage = no
	# keep files open = auto
	# directory to monitor = /host/sys/class/power_supply

```

but yet i can’t see it.  
Powersupply → BAT0 is only showing capacity  
Sensors is only showing voltage

You are right. It’s very weird you get the message “section is not used” by default.

```

current\_now , voltage\_now and power might be good, but i believe without AC current is 0.  
How do i check their value?

> That’s the guide i’ve followed but without luck, the “Sensor” tab is disappearing

Just realized that we are discussing two collectors:

- Sensors ([bash](https://github.com/netdata/netdata/tree/master/collectors/charts.d.plugin/sensors), [python](https://github.com/netdata/netdata/tree/master/collectors/python.d.plugin/sensors))
- [Linux Power Supply](https://github.com/netdata/netdata/tree/master/collectors/proc.plugin#linux-power-supply)
