Hello All,

i run a 8 Node Proxmox 6.3 Cluster with 3 FreeNas Systems via NFS.
Sometime i got some high IO Wait and the Guest will slow down.

Wich is the best Way to find the Guest with the highest IO?

Thanks a lot.
 
quick n dirty / live: run iotop on hosts and take look.

on the long run: your monitoring should be able to show this data. we are using zabbix e.g. that could show graphs of io within any time range. any other monitoring should do.
if you just want graphs take a look at e.g. munin (or others)
