[BUG] Incorrect memory stats on the landing page

[TCBWZA]

Description

If you compare the PVE default memory graph and the one on Promenux The ZFS Arc and Available do not work in Promenx. (I've noticed I am on an older version but am unsure how to move to 1.2).

Steps to Reproduce

1. Open PVE default page, select summary
2. Open Promenux deselect total and available from the memory graph

Expected Behavior

I expect the numbers to the the same or similar. I expect the selection items in the graph to work the same way as the ones in PVE Summary

Screenshots (Required)

Environment

• Operating system: PVE 9.2.3
• Software version: ProxMenux Monitor v1.0.1
• Other relevant details: System is an AMD AM4 5700g

Hi @TCBWZA, thanks for reporting this issue.

I see you're using version 1.0.1.
That version is a bit old, and this problem has been fixed in later versions. Please update to a newer version and let me know if it works.

Hi @MacRimi

I have upgraded and the ZFS ARC value seems to be wrong. If I check my two graphs as betfore, it looks like the ZFS ARC value it the current value rather than historical ones.

Proxmox Summary

Promenux overview

The most recent value on the summary graph is 11.5.

Version: ProxMenux Monitor v1.2.2

Thanks for the detailed report — that comparison with your Proxmox Summary chart was the key. The Memory Usage chart was reading the live ZFS ARC value and stamping every historical point with it, instead of using the actual ARC history (arcsize) that PVE 9.x exposes in its RRD. Fixed on develop now — the line should follow the real series and match what your Proxmox Summary shows. Available in the next beta build.
