No CPU and RAM stats after PiOS 11 to 12 update

[klour]

Hi,
First of all I really love your work. You created an easy to use and good looking informative dashboard for managing and monitoring Raspberry PIs. In the meantime it runs in my home network on three PIs (1B, 3B and 4B).

I just updated my most important Raspberry (the 4B, running a PiHole DNS and a Wireguard server) from Bullseye to Bookworm. Yes I did it an upgrade of an existing system (which I know is not recommended. I am an IT guy, and know what to do. Therefore I did a complete backup ;-). Anyways, I just gave it a try, because some years ago the Buster to Bullseye upprade worked for me also without any issues. An now, since the Bullseye to Bookworm update is done, I can say, the upgrade worked once again without any notable issues. Except this one:

The Raspberry-Pi-Dashboard is working. Login an meta PI and OS information are gathered and display as well. However the only things which do not work are the CPU stats and the RAM stats. See screenshot. What could be the reason? Any hints?
If I manually click the "play/pause" button, the string "Will be updated" is visible and the counter seems to start working. However no update of the values take place.

Bookworm came with a new version of PHP (8.2.7). Maybe thats the reason?

/var/www/html/ permissions are all fine, I double checked them.

Thanks in advance for you help.

Many thanks @klour for your feedback! Glad to hear!
And also thanks for testing the new update. Of course you can always give upgrading a try. I haven't done the update to the new OS on my RPi yet.

Anyway, what you report looks interesting. There must be something changed on how the CPU and RAM information is retrieved from the system or the permissions required to do so.

What you can do (which would be the easiest and fastest way to find out what is wrong) is to call the server backend that is responsible for gathering the information manually. You can do that by just opening <yourDashboardURL>/backend/sys_infos.php in your browser.

Please post the output if you get any, thank you! I'm curious!

Hi @klour ! That helped a lot! In fact, it looks like the issue of the dashboard is due to some code incompatibility with PHP 8.2.
Thanks again for reporting! A patch will be released today.

See release v1.1.4 for a fix. Let me know if there are any further issues. Thanks!

Hi @femto-code,
just installed v1.1.4. The values and bars for CPU, Temp and RAM are populating again.
Great work sir!

However I see some "unattractive" values for 1min/5min/15min CPU load. Looks like they need to be truncated (see screenshot). Not sure if this is possible, since I think the whole data type topic was the root cause of my reporting in course of php 8.x. But I assume truncating should always be possible. What do you think?

Thanks for testing @klour ! Highly appreciated!

And yes, I simply forgot to round the numbers and limit the decimals displayed. That's easy to fix, I'll release a fix soon!

@klour The release is coming today. Sorry for the delay...
