performance monitoring

I want to monitor IO Wait, also called wa in top. I have a script that outputs the values, which works perfectly inside the VM: $ sh check.sh 2024-10-28 06:03:11 - IO Wait: 18%, Load averages: 1.13, 1.15, 1.26 2024-10-28 06:03:13 - IO Wait: 21%, Load averages: 1.20, 1.16, 1.27 2024-10-28...

Hi, Since yesterday all performance graphs (CPU usage, Memory usage, ...) are showing blanks in the Proxmox GUI, for hosts, VMs and CTs. I can still see the real-time stats in the uptime box but I would like to have trend info back as well. If someone has anyone ideas, please let me know...
