We would like to add monitoring library to Operator-SDK or Kubebuilder, based on https://github.com/machadovilaca/operator-observability.

It includes a set of opinionated observability utilities and wrappers for Kubernetes Operators using Prometheus Golang client.

The goal is to help developers of Kubernetes Operators instrument their operators, while avoiding common pitfalls and mistakes, and keep their code base organised, clean and well documented.

Add to the code the metrics name linter in a lib format.
