Hi,
I wanted to monitor disk IO and R/W on all of our oVirt centos 7.3 hypervisor hosts, but
it looks like that all those files are empty.
For example:

I thought, I can get my needed values from there, but all files are empty.
Looking at this post: http://lists.ovirt.org/pipermail/users/2017-January/079011.html
this should work.
Is this normal on centos 7.3 with oVirt installed? How can I get those values, without
monitoring all VMs directly?
oVirt Version we use:
4.1.1.8-1.el7.centos

We have a very nice integration with Elastic based monitoring and logging -
why not use it.
On the host, we use collectd for monitoring.

Hi Yaniv,
thank you for your answer! I haven't known, that there is already such a monitoring
tool on ovirt.
We will sure give it a try, but we have already in our environment a monitoring tool,
that's why I wanted to add those values, too.
How does collectd get this data from libvirt, when the corresponding cgroup values are
empty?

How does collectd get this data from libvirt, when the corresponding
cgroup values are empty?
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 have a very nice integration with Elastic based monitoring and logging
- why not use it.
On the host, we use collectd for monitoring.

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Perhaps this is an outdated way and metrics should be collected in a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.

yes, still the same issues with oVirt 4.1.7 and CentOS 7.4.=20

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

We use oVirt 4.1.6 on 7.4 of course.

E.g. integrated to oVirt or "admin can send metrics to ELK"?

We provide the required scripts to install OpenShift with the EFK stack,
configure it and the hosts with all relevant details to connect the two.
Note that the metrics store also processes the engine and VDSM logs.

Good to know. But if I still want to use netdata instead EFK? Some info
about how to get blk io metrics from libvirt and/or how to enable
cgroups metrics. Anyone?
Thanks.

Get netdata to query libvirt for the IO parameters directly. It should be
configured with authentication against libvirt (the same password VDSM
uses).

I thought, I can get my needed values from there, but all files are
empty.
Looking at this post:http://lists.ovirt.org/pipermail/users/2017-January/079011.html
this should work.
Is this normal on centos 7.3 with oVirt installed? How can I get those values, without
monitoring all VMs directly?
oVirt Version we use:
4.1.1.8-1.el7.centos
Hi Florian. You find answer on this? Today released netdata
1.9.0. New
feature is disk i/o and network metrics per VM - and all of this not
work with oVirt from bootstrap. I created issue (netdata #3144
<https://github.com/firehol/netdata/issues/3144>) and network metrics is
winned. But disk metrics is just empty - as you sayed before (oVirt
release 4.1.7).
