Splunk APM with Azure App Service Running Java

[wouldchuck]

I've been struggling to decide the best method to instrument a Java web app running on Azure App Service. There's plenty of documentation for AKS services, ECS services and so on. There's even documentation for .NET services running as an Azure App Service but nothing for my use case. 

Is there any documentation available for this specific scenario? I've read and re-read the Java APM documentation but I still feel a bit lost. 

Thank you for any help and suggestions!

We are encountering the same issues with Azure App Service and our Java apps. Infrastructure metrics are totally fine.
