Disk usage

Hello,
Today I’ve noticed that the used space in the SD Card is slowly increasing. Does your system show a similar behavior?
Currently running PiAware (SD Card) 5.0.

system-localhost-df_root-180d (1)

I can’t say it does.

You could do a cleanup on your system with the following commands :slight_smile:

Sudo apt-autoremove ( this will remove no longer used packages)
Sudo apt-get clean ( this will remove the downloaded packages from the local storage). If they are needed in the future they are automaticly downloaded again.

Nope.

There is something really wrong on the device. That fast increase is not normal. Having the feeder only should not take more than 2-3 GB stable.

try running the command

sudo du

from the root folder, this might give you an idea which folder contain the files taking that much.

More options on that command:

Linux commands: du and the options you should be using | Enable Sysadmin (redhat.com)

After cleaning log files in /var/log it’s better, have to check this more often.
Thank you all for the information.

Yeah but it’s still not normal having such an increase after few months.

That’s mine after 2 1/2 months, using a 64 GB SD card
And beside the feeder i also have WeeWX (weather station software) with Apache and MySQL running together with an InfluxDB/Grafana instance on the same device

I’d thought logrotate should keep your files to a reasonable size. Just deleting logs has not fixed the issue which will recur; what is making the logs grow so fast. Some info/warning/error that is repeating frequently ?

Before deleting the files it would have been good looking on their list…

But now it’s too late

I’m monitoring the logs size and next time I will save then before delete.

After 9 days I haven’t seen any major increase in used space.
In the daemon.log I can see a lot of " Can’t connect to 978 source (127.0.0.1:28380). Waiting 5 second…", is there any way to stop this process?

if you are not using UAT 978 ( USA only) then you can use the following commands to disable the 978 reciever.
If you ever want to add a 978 reciever you can use the 2nd part of the commands below.

9.2 - If you want to run 1090 Mhz only
In this case, you will need only one dongle, but you will have to disable dump978-fa by following command

sudo piaware-config receiver-type rtlsdr
sudo piaware-config uat-receiver-type none
sudo systemctl restart piaware

To re-enable dump978-fa (requires an additional dongle for dump978-fa)

sudo piaware-config uat-receiver-type sdr
sudo systemctl restart piaware

You should have log messages in journalctl in memory.
Really there is no need for /var/log very much …
I’d just

sudo apt remove rsyslog

And get rid of redundant logging.

I will show your statement to the Radarbox team :slight_smile:
On my end this is the one causing most traffic in my var/log without giving much value. Therefore i’ve moved this particular log to Ramdisk and write it once a night to disk.

Checking my CPU use wioth and without Radadrbox24.com active. It takes a lot of CPU when I open the site on my Macbook.

Radarbox24.com open

Without Radarbox

It seems Radarbox is taking a lot of CPU%

Does everyone have the same experience? Noticed it before, but after reading this thread I decided to check it again.
