Routing Alerts to AlertManager from Thanos Ruler - How to set custom PromQL address?

[diranged]

Is your proposal related to a problem?

When we have the thanos-ruler pods pointing to a thanos-query-frontend endpoint, our alerts get a nice friendly Alert Source: https://…./query/… label that helps our developers get right to the source of the alert.

However, when we run the thanos-ruler pods against either Amazon Managed Prometheus or Grafana Cloud, we get a shortened URL that just gives us a query-path .. the problem is neither Grafana Cloud nor Amazon Managed Prometheus provide a /graph endpoint.

Describe the solution you'd like

It would be ideal if there were a few options here..

1. Allow us to templatize the URL to anything we want (with the alert query as an argument).
2. Have some native understanding of the Grafana /explore endpoint URL structure and allow us to route to that.

Do you have such an template to share?
