Cloudron v9: huge disk I/O is this normal/safe/needed?

[imc67]

Description

I noticed since v9 on my 3 Cloudron-Pro instances with the new graphs that the Disk I/O is non-stop average at Write ~ 2.5 MB/s and one even at ~4MB/s. This seems to me extremely high as the 3 servers are IMHO not really highly productive. The total Write in 24 hours is about 4-7TB!!!

Steps to reproduce

Have a look in your graph

Cloudron Version

9.0.12 and since last night 9.0.13

Ubuntu Version

Ubuntu 22.04.5 LTS

We have even more I doubt our server wrote or read so much. Must be something wrong with the reporting, investigating...

But at least your Writ I/O graph/speed is almost zero?!

Also in the Netcup SCP it shows, so it seems there is seriously something wrong?

(The last part of the graph is not representative, zooming in to 6 hours is straight line)

I checked many servers and it's mostly under 1MBps all the time . Does 'docker stats' show anything interesting (if it's a container that is hogging cpu)? Not sure what else you have installed on your server?

Also, the total read/write counters are cumulative counters maintained by the kernel since boot time.

'docker stats'

it's impossible to have a view with this, every second tens of docker containers are created (cron?) so it keeps listing and growing.

Is there a proper way to do some inspections with disk I/O in mind? Or shall I give you access to have a view?

Hello @imc67
Could it be that you simply need to zoom out of your terminal or make the window larger?
Had the same first thought when running this command but when resizing the window or zooming out:
