Hi Marek,
In fact all the data you need is already collected by oVirt/VDSM itself
and saved into the DWH database.
I configured sql_exporter for prometheus which does queries on the DWH
database to gather the data I need.
This is exported to prometheus, and there I can query all the data and
do some alerting on for example I/O usage.

hi,
i have prometheus based ovirt hosts monitoring (node_exporter,
smartcl_exporter, ipmi_exporter)
https://prometheus-community.github.io/ansible/branch/main/ and alerts
from https://samber.github.io/awesome-prometheus-alerts/
after i started this monitoring i found that one VM is overloading
local storage (so i must check IO limiting documentation as a homework
:) )
but my question is
how do you monitor IO traffic per VM? (IOPS, read/write traffic,..)
some qemu/libvirt exporter? some custom text file + node_exporter?
thanks for tips
Marek
