CPU usage graph - did something change in July '25?

[johnha]

The display looks so much different than before, much more fine grained and also my server and habits didn't change, so I wonder why the apparent huge increase in CPU usage displayed. Perhaps the values are recorded much more frequently? But that would only explain the "Maximum" graph.

This is for Year (Maximum):


This is for Year (Average):

Well, when did you upgrade to 9.0? You did upgrade, right?

Reading https://pve.proxmox.com/wiki/Roadmap I find:

"Increase the RRD guest metrics aggregation window to provide greater temporal granularity." ...

Ah great, thank you for that link. I guess I didn't have the right keywords to search for that. I'm on 9.0.11 although can't quite remember when I upgraded (within the first month of 9 being out).. But tbh I won't upgrade again so soon, my host became unbootable and nightmare to solve. First upgrade issue I've had and I started with v4.

Although the question remains, I haven't changed how I use my host, so why are all the metrics so much higher than before? Or were the past data not as accurate as now?
