[ovirt-users] oVirt Metrics Store Installation - Error during SSO authentication

2019-10-15 Thread Markus Schaufler

Hi,

oVirt 4.3.5
changed certificate to one from an official CA
configured active directory auth
no kerberos / no ldapS

as per: 
https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.3/html-single/metrics_store_installation_guide/index#Installing_metrics_store

During installation of the metrics store following error appears:

Double-checked the credentials in "metrics-store-config.yml" and

Any hints on this?

[ovirt-users] ovirt metrics - vm dashboard not working

2019-06-03 Thread Jayme

I finally managed to get oVirt metrics store running.  I loaded sample
dashboards, searches and visualizations in to Kibana from
/etc/ovirt-engine-metrics/dashboards-examples.  When importing searches and
visualizations there are warnings about missing index patterns.

It appears that the "VM" dashboard is completely broken, no stats are
showing on it at all including simple stats such as running VM count.

The other two dashboards Hosts and System are working and showing all stats
(sans VM count on the host dashboard).

I believe I have a cash here of either missing indexes or potentially an
issue with the example dashboards?  I can see that collectd is running on
all hosts and has the virt plugin loaded.

What part of the config is responsible for suppling the VM
information/indexes?

[ovirt-users] ovirt metrics ansible error

I'm running in to this ansible error during oVirt metrics installation
(following procedures at:
https://ovirt.org/documentation/metrics-install-guide/Installing_Metrics_Store.html

This is happening late in the process, after successfully deploying the
installation VM and then running second step from the metrics VM.

2018-06-11 Thread Shirly Radco

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 do not think it's included in 4.1. I can only see it in the master
branch, see [1]. Adding Ravi. Ravi - is it planned to be in 4.1? If not,
perhaps the blog post should mention this.

You can try this by using the nightly snapshot [2]. Obviously do not do
this on a production setup.

Or you can use the version without sso.

2017-07-11 Thread Arsène Gschwind


Hi all,

I'm trying to setup oVirt metrics as described at 
https://www.ovirt.org/develop/release-management/features/engine/metrics-store/ 
using SSO.

My oVirt installation is based on Version: 4.1.3.5-1.el7.centos.

I'm missing the SSO tool called ovirt-register-sso-client as written in 
the doc to register new SSO client. I couldn't figure out which package 
contains that tool, is it included in the latest distribution ?


Thanks for any help.

rgds,
Arsène

Re: [ovirt-users] oVirt metrics

Hello!

very nice implementation - and very good blog entry.

IMHO a very important metric should be made available: IOPS.

IOPS are a very important factor when using shared storage among a
cluster. It is a key indicator for identifying issues and performance
bottlenecks and also having a base for scaling proper storage devices.
Beeing able to display IOPS per VM would be a great benefit for large
scale enterprises.

best,
 Dominique

[ovirt-users] oVirt metrics

2016-07-13 Thread Yaniv Bronheim

Hi,

In oVirt-4.0 we introduced integration with metrics collectors, In [1] you
will find a guide for utilizing your environment to retrieve visualized
reports about hosts and vms statistics.

I encourage to try that out and send us requests for additional valuable
metrics that you think vdsm should publish.
This area is still work in progress and we plan to support more
technologies and different architectures for metrics collections as
describes in the post. This will follow by additional links in the post
([1]) that describe how to do so.. stay tuned.
