KubeVirt metrics

This document aims to help users that are not familiar with all metrics exposed by different KubeVirt components. All metrics documented here are auto-generated by the utility tool tools/doc-generator and reflects exactly what is being exposed.

Developing new metrics

After developing new metrics or changing old ones, please run make generate to regenerate this document.

If you feel that the new metric doesn't follow these rules, please change doc-generator with your needs.
