memory usage

Quit normal. If you study your own picture you will notice that must of the consumed RAM is cached.
You can easily confirm this by:
free && sync && echo 1 > /proc/sys/vm/drop_caches && free
 
i never checked it befor, i integrate now both proxmox machines in our monitoring and so i was wondering why its always near 0. so you mean i can ignore this and can delete this sensors yes?

Free memory on *nix is the sum of free memory + buffers + cached. All memory not allocated for running processes is used as disk cache so you cannot use the value of free memory as a metric to conclude whether the system is memory constrained or not.
