How to see energy rate

maxdd · March 29, 2021, 11:57am

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

[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 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”

maxdd · March 30, 2021, 6:33am

Here is the command

~/docker/netstat$ docker logs netdata 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)

vlvkobal · March 30, 2021, 7:06am

Please check if

[plugin:proc]
	/sys/class/power_supply = yes

maxdd · March 30, 2021, 7:35am

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

maxdd · April 2, 2021, 6:43am

Any help? @ilyam8 @vlvkobal

vlvkobal · April 2, 2021, 8:23am

What are the contents of /host/sys/class/power_supply/BAT0?

vlvkobal · April 2, 2021, 8:26am

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

maxdd · April 2, 2021, 8:46am

Where do i see the content of host/sys/class/power_supply/BAT0 ? you mean from the webpage or the conf? or what?

vlvkobal · April 2, 2021, 8:48am

From the inside of the container. ls -al host/sys/class/power_supply/BAT0.

maxdd · April 2, 2021, 9:11am

bash-5.0# ls -al host/sys/class/power_supply/BAT0

vlvkobal · April 2, 2021, 12:42pm

Well, it’s not the information I wanted to see. Please do ls -alL instead of ls -al.

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

ilyam8 · April 2, 2021, 1:03pm

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, python)
Linux Power Supply

Let’s don’t mix them up and try to figure out what is missing/why doesn’t work (?) Linux Power Supply.

maxdd · April 2, 2021, 1:41pm

makes sense to me, Linux Power Supply is only showing battery capacity then

vlvkobal · April 2, 2021, 1:42pm

There are no energy_* files in the directory. That’s why you don’t see the corresponding charts in the dashboard.
