RAM usage indicator - feature suggestion

[150d]

Hello,

on my Proxmox machine the "RAM usage" indication is always very high, at least around 80%, even though my VMs are allocated much below that. As I understand, the rest is used for ZFS cache, thus the high value is completely normal.

But why is the indicator either yellow (usually interpreted as "warning") or red ("error")?

Would it make sense to split this indicator in two, one for "in use by system/VM/LXC" and one for "ZFS cache", neither one would have to be orange/red in a case like mine?

Regards

With default configs at 80% RAM utilization KSM and Ballooning kicks in. KSM will then deduplicate your RAM which will slow down your node. And ballooning will steal RAM from guests to get more free RAM for the host. So the bar turns red at 80% because it can be bad when over 80% utilization with enabled ballooning or KSM.
