Hi,

yes, still the same issues with oVirt 4.1.7 and CentOS 7.4.

Whole cgroup directory has empty files.

Actually at the moment, we are blind when it comes to disk IO, only our NetApp give us IO values, but these are per NFS share and there are a lots of VMs on it.

A solution would be great here.

Betreff: Re: [ovirt-users] Empty cgroup files on centos 7.3 host

Specifically for IO statistics, VDSM reads the values from libvirt[1].
cgroup limiting is possible if you define it, but is unrelated.
Also note that 7.3 is a bit ancient, I'm not sure how supported it is with
latest 4.1 - which I'm sure will pull new dependencies from 7.4 (for
example, libvirt!).

We use oVirt 4.1.6 on 7.4 of course.

Where I can see IO stat? I never see this on oVirt manager.

How can I enable cgroup blk metric collection?
Perhaps this is an outdated way and metrics should be collected in a different way and it should be applied in the netdata project?

Thanks.
