This is a Prometheus exporter that aims to pull some of the data that is provided by the OpenStack Exporter but directly from the database.
The existance of this exporter is an OpenStack bug. At scale, the APIs become extremely sluggish at operating with large number of API requests.
In addition, certain queries can be done far more effectively directly without going through many different API calls. The goal of this exporter is to be operator-facing and providing high performance for large scale clouds.
Service database APIs, SQL definitions, and integration schema fixtures are maintained in openstackdb. This exporter owns Prometheus collectors and metric-output tests. Query changes belong in openstackdb; update the pinned module version here after validating compatibility.
