Custom Grafana Dashboard - Combined SLO - Availability

[Fran-78]

Ive created a few SLO's per namespace1 - based on 4 apps (app1, app2, app3, app4)

(avg_over_time(pyrra_availability{slo="http-client-requests-errors-app1-namespace1"}[14d]) * ignoring(slo) avg_over_time(pyrra_availability{slo="http-client-requests-errors-app2-namespace1"}[14d])) * ignoring(slo) (avg_over_time(pyrra_availability{slo="http-server-requests-errors-app3-namespace1"}[14d]) * ignoring(slo) avg_over_time(pyrra_availability{slo="http-server-requests-errors-app4-namespace1"}[14d])) * 100

This prometheus exp works just fine.

I need a Grafana Dashboard with some templating involved for the namespace and we can call it combined-slo-availability - with just a dropdown menu for all the different namespaces (namespace1, namespace2 and so ...)

Any suggestions - my templating aint the best - i know i have to use the namespace=$namespace depending on how the metrics are coming in. Im also not really in the mood to create prometheus rules for this as it consumes alot of resources / cpu for calculations.
