How to register Rancher managed Kubernetes clusters in Argo CD

Registering Rancher managed clusters in Argo CD doesn't work out of the box unless the Authorized Cluster Endpoint is used. Many users will prefer an integration of Argo CD via the central Rancher authentication proxy (which shares the network endpoint of the Rancher API/GUI). So let's find out why registering clusters via Rancher auth proxy fails and how to make it work.

Hint: If you are just looking for the solution scroll to the bottom of this page.

Why do i get an error when running argocd cluster add?

    ## Frigate Mobile App Notification

    This blueprint will send a notification to your device when a Frigate event for the selected camera is fired. The notification will initially include the thumbnail of the detection, but will update to include actionable notifications allowing you to view the saved clip/snapshot when available, or silence the notification for a configurable amount of time.

    With this blueprint, you may send the notification to multiple devices by leaving "Device" blank and instead use a [notification group][1].

CPU: percentage of limit

A lot of people land when trying to find out how to calculate CPU usage metric correctly in prometheus, myself included! So I'll post what I eventually ended up using as I think it's still a little difficult trying to tie together all the snippets of info here and elsewhere.

This is specific to k8s and containers that have CPU limits set.

To show CPU usage as a percentage of the limit given to the container, this is the Prometheus query we used to create nice graphs in Grafana:

sum(rate(container_cpu_usage_seconds_total{name!~".*prometheus.*", image!="", container_name!="POD"}[5m])) by (pod_name, container_name) /
