Hello everyone, I am currently working on setting up a self-hosted LGTM stack and am a bit stuck on how to setup the ruler. We are wanting to utilize the Grafana Cloud alertmanager with our self-hosted rulers and during our investigation, we noticed that our currently running mimir(prometheus) Grafana Cloud instance comes with pre-configured alerting and recording rules. Is there some place where these rules are located because we want to store them on our self-hosted rulers.
Furthermore, what is the recommended approach to storing these rules. I noticed the docs mention using a configmap or external storage like S3. Is there a guide somewhere on how to to store alerts in S3?
Thank you for any and all help!
