[PVE-User] Cacti Monitoring of Proxmox Cluster

[Daniel]

Hi there,

i tried to monitor my Proxmox Cluster with Cacti.
I just uses the Percona System Templates to generate graphs. My Problem here is that I don’t get any Disk Results (IOPs, read/write u.s.w)

I just wanted to know which Device I have to choose to get an overall view on Disk Writes and so on.

Just for an examples – I have these LVMs:

# lsblk

Please not, I want to read the overall Disks and not the Disks per VM.
Any glue?
