RRDData don't return all datas

[slade991]

Hello,

I'm trying to pull RRDDatas for a vm with go-proxmox, however the data are not complete :
metrics, err := vm.RRDData(context.Background(), proxmox.TimeframeHour)

returns :

The datas are always the same as it only returns the "max" and there is a lot of stuff missing. If i compare it to :

pvesh get /nodes/mtl1/qemu/138/rrddata --timeframe=hour --output-format=json

which returns :

Here we have a lot more informations :
cpu, diskread, diskwrite, mem, netin, netout

Would it be possible to add the rest of the data instead of only MaxCPU, MaxMem, Disk and MaxDisk ?

Let me know if i'm missing something.

After checking it seems it have been added in this PR: #87

but it haven't made it's way to main ? I can't seem to have access to the branch "vm-updates".

if you are looking for Disk Size, its not computed, for Ceph I had to update code, sharing information if you would like to try out. , https://forum.proxmox.com/threads/vm-shows-0-0-disk-usage.114808/#post-587791

I'm looking mostly for cpu, ram, netin, netout, diskread and diskwrite.

I can live without disksize, i didn't intended to show it anyway :)

However the other datas would be great.

I kinda messed my commit as there is irrelevant things in it and it is messy, but the changes i did on my fork fixed the RrdDatas. You can see the commit here: slade991@1ddcfd6
