Hi. I also use Zabbix here. Its problem is that it collects metrics in real time, this is not its function. There are other alternatives like Elasticsearch + metricbeat, but from what I've tested, it's very heavy and uses a lot of disk space lol. I never used Prometheus, I found it interesting. I'll do some tests. @Patrick Dubois <pat@pdubois.com> How often do you collect information with Zabbix? Every 1 minute? Because for example... for the information to be used correctly for analysis, we have to have an IO load of at least 1 continuous minute so that Zabbix can collect the correct information. Cheers!

For detailed monitoring I use Zabbix. This way I get detailed metrics on my hypervisors, VMs as well as my network storage.
If a machine starts generating large IO I get alerts highlighting the responsible machine as well as the impacted services. For example, you might get high IO on a VM but also the correlated high latency on systems sharing the storage.
Sometimes users will report the the high latency, masking the real problem so it's nice to have a holistic view of the entire environment.

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
