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?

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

Looking at this post: [ http://lists.ovirt.org/pipermail/users/2017-January/079011.html | 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 BR Florian _______________________________________________ Users mailing list [ mailto:[email protected] | [email protected] ] [ http://lists.ovirt.org/mailman/listinfo/users | http://lists.ovirt.org/mailman/listinfo/users ] BQ_END
