How to view used disk space in Summary?

[VerticalTechnik]

Good day all.. maybe a stupid question but I can not figure out how to display the used disk space in the Summary Graph..
Anyone got an idea how to do that or is it only possible to check used disk space using the Terminal?

What summary? Datacenter? Node? Vm? LXC?

In case you mean VM summary, that is not possible as the PVE host doesn't know anything about whats happening inside the VM and it can't see the filesystems there.

How come that the VM can see the CPU and RAM usage, but not the disksize usage?

A filesystem can only be mounted once to an OS. If you mount it to another OS you would corrupt the data on it. So you can't access a filesystem at the same time on the host and on the guestOS. Without some kind of guest agent running on the guestOS that reports filesystem metrics back to the hypervisor this won't work...and the qemu-guest-agent can only report RAM usage but not disk usage.
