Description Chetan Nagarkar 2019-02-20 22:14:54 UTC 
Description of problem:
Support for Prometheus in RHV metrics collection or discussing support of https://github.com/rmohr/ovirt-prometheus-bridge for collecting RHV metrics.

Version-Release number of selected component (if applicable):
Red Hat Virtualization 4.2.8

Additional info:

As per Red Hat documentation, Prometheus is used as an external alerting component. CloudForms integrates Prometheus alerts for use with OpenShift Container Platform.

Reference: https://access.redhat.com/documentation/en-us/red_hat_cloudforms/4.6/html/monitoring_alerts_and_reporting/integrating_prometheus_alerts
 
More information is required regarding support for Prometheus in RHV metrics collection.
Comment 2 Shirly Radco 2019-06-17 10:59:38 UTC 
Will adding collectd write_prometheus out plugin,
that will display collectd metrics in the way Prometheus can scrap them,
be sufficient for customer?
Comment 6 Jean-Louis Dupond 2020-09-16 11:48:07 UTC 
Any update on this?

As we see Prometheus is getting more and more the industry standard for metrics, it would be great to be able to hook in Prometheus into oVirt for its metrics.
The Engine should provide some /metrics endpoint so metrics can be scraped from it.

sql_exporter config

I found a (temporary) solution that uses the DHW PostgreSQL data to generate Prometheus metrics that can be scraped.

It uses https://github.com/free/sql_exporter with the config in attachment.

All it needs is some query optimisation, and it works quite well then!

We are past 4.5.0 feature freeze, please re-target.
Comment 11 Michal Skrivanek 2022-04-08 16:28:20 UTC 
no update for a long time, didn't make it for 4.5, workaround in comment #8 looks...decent enough, closing
