Dear users,

I would love to get some feedback if someone has tried to install and use the oVirt metrics store, released in 4.2, for collecting metrics and logs, based on Elasticsearch, Kibana, Collectd and Fluentd on top of OpenShift.

https://www.ovirt.org/develop/release-management/features/metrics/metrics-store/

How did the installation go? Are you actively using it?

And any other feedback would be much appreciated.

Best regards,

I have, and while I can say that it works, it was far from easy! I can't remember all of the gotchas I had to go through but most of them stemmed from the fact that I tested it all on a three node oVirt HCI cluster that was actually VM's with nested virtualization, which meant fairly limited resources but eventually got it working.

Being completely new to OpenShift, a guide that needs more work is the single sign on from oVirt to OS. The instructions are way too unclear for me, and wrapping your head around how the login and permissions system works in OS took a while, to create an equal 'admin' account to log in with.

Second, isn't OS just an above layer of kubernetes under it, or is that a misunderstanding on my part? If it is though, where is the administration page for Kubernetes in all of that? I'm thinking in the sense of how you can add more nodes to continue building a larger cluster for containers.

OpenShift is much more than just Kubernetes, but specifically this instance should be used solely for metrics and logging and is therefore specifically installed as an all-in-one installation. 

Y. 

OK, yeah, for sure! But is there no Kubernetes console in this all-in-one installation?

/K

But once everything was setup and able to log in to the Kibana interface and loading up the dashboards you've made, I was really impressed with how much data you got visualized for free. Thumbs up!

/K
