VM summary page shows data from previous VM

[SteveITS]

I deleted a VM this morning, and created another this afternoon that defaulted to the original VM's ID. It looks like the VM's Summary page shows data from the old VM? In Month view there is data from before today, until the old one turned off, though of course none yet for today (for future readers, today is 2025-05-14):

Don't worry, the date and time are present on each port.

indeed; this is normal for Proxmox VE.

Interesting, I would think it would discard the old data. Or maybe just use the next higher ID and wrap around when it needs to.

For us I guess it doesn't matter as we're the only ones who can see it. Just seemed wrong.

Just seemed wrong.

Bug report and feature request should go to https://bugzilla.proxmox.com. This is the community forum, which is fine to discuss all kind of issues, but Proxmox staff typically asks to report issues/features at their issue tracking system.

If you want a workaround (I've used it before):

The RRD (Round Robin Database) data used for those GUI stats is stored in a file: /var/lib/rrdcached/db/pve2-vm/<VMID>
So if you use:

rm /var/lib/rrdcached/db/pve2-vm/<VMID>

Woosh its gone!

BUT probably on a cluster it could be easily recreated if the VM exists somewhere else in that cluster.
However seeing that completely removing a VM is (usually) on a test/rd VM - this is not (again usually!) a problem.

Hmm well since it’s assigned perhaps not 13 more years… /s At least I’m not the first to wonder.

In our case either a client leaves/cancels or we’ve migrated to a newer/different OS. Usually the latter so far but hopefully Debian will be more upgradable.

It’s not critical enough for us to go deleting files but it seems like it’d be easily confusing. I just see no reason to keep the old data. One can’t ever see it (?) without creating a new VM…
