Weird RAM usage reporting.

[landis]

I noticed recently that my proxmox servers does not report the correct RAM Usage. It shows up differently in all methods I try.

Example 1: Default PROXMOX Dashboard



Example 2: free -h (command)



Example 3: Htop live results



Im not too sure on how to continue, could this be a bug ?

What can be used to accurately measure the RAM usage on hosts?

PVE Version: 8.1.4
Platform: x86_64

No, that's all correct.

free and PVE show the correct usage. Why htop is showing the green bar, i don't know, yet the yellow bar in htop is the 90% used, so the actual usage of ram is in all 3 examples roughly 90%.

In general, please familiarize yourself if not already done with https://www.linuxatemyram.com/

That was the mind boggle. The htop bar showed the correct usage but showed 9.4GB.

I was doing some research into the ram and completely forgot about disk caching. Thats when i popped in here to find your link linuxatemyram.com

That's when everything made much more sense lol. I had a chuckle as it was something so simple that i had forgotten.

Thank you for your response and links. Greatly appreciate that you took the time to respond
