Just thinking, prometheus_ex uses ETS to store the metrics, so you might not even need an additional metrics app in an umbrella setup. I can’t say for sure but if all apps in the umbrella setup use the prometheus_ex package directly, they should all use the same ETS tables and therefore have a shared metrics list.

I use prometheus.ex in a very similar way but I use the Prometheus.Metric.Summary type of metric:
Summary.declare(
name: :vm_check_duration_seconds,
help: "VM Check duration in seconds",
labels: [:tenant, :hypervisor],
)
When I later call Prometheus.Format.Text.format I’m getting the _sum and _count metrics tagged with the labels correctly.
However, I’m not getting the quantiles. Does anyone know how to enable quantiles?

quantiles just aren’t implemented (yet). I don’t use it because they do not aggregate. PR is welcome though.

Thanks for answering my question.
I took a quick look at the source code. Although I’d love to contribute and learn Elixir better, I see a lot of meta-programming in the code which I don’t understand yet so I’m not able to contribute at this time especially a large feature like quantiles.
I hope to keep learning Elixir so maybe one day I will know enough to contribute.
