Interrupted graph in VM

[faluyt]

Hi,

I am currently running Proxmox on a server with some VMs. Sometimes, I see the interrupted graph of VM detail as screenshot below:




I can confirm that even the graph showing interrupted, the VMs and the server are running perfectly fine without any network disconnect/reboot...

Here is pveversion:

This server running quite an old version of proxmox (v5), but on some other servers running newer version (proxmox 6 or 7), I sometime also notice this issue.

I would like to ask what can cause this issue and how to fix it? Thanks in advance.

Hello,

I would like to ask what can cause this issue and how to fix it?

Did you check the syslog at that time? You can use journalctl e.g.,:

journalctl --since "2023-08-01 05:30" --until "2023-08-01 09:00" > /tmp/Syslog.txt

You may have to edit the date/time in the above command.
