Summary Graphics breaks during backup of VMs

[VDNKH]

Greetings friends of the proxmox community

I have a question.

I have a nightly backup task of my virtual machines, but I realized that the graph of cpu, ram memory and network usage. They all kind of break.

Do you know what it means?

Attach an image of the server

Hi,
it might be that the server is too overloaded and pvestatd (service for statistics) is not able to update anymore. You can check your /var/log/syslog and journalctl -u pvestatd.service for errors. There is a build of QEMU that's less aggressive during backup (will be configurable on a per-job basis in a future version of Proxmox VE). A VM needs to be shutdown/started after installing the new version (reboot is not enough!). You could check if the situation is better with that build.
