Thanks for raising this issue @jaywithersbrewin.

Looking over the MSFT documentation, in order to configure Prometheus metrics on an AKS cluster the Azure Monitor Workspace (which creates the MA_* resource group, as well as the DCE and DCR) needs to be created beforehand. The Rest API does not handle the automatic creation of it just from enabling it.

For guidance on how to setup Prometheus logging on your cluster the MSFT docs have a great guide with example Terraform modules.

I'm going to close this issue since there aren't any changes we can make to the resource for this. The linked guide should provide clarity on how to setup Prometheus logging and for any further configuration questions the Community Discuss forum is a good place to look through.
