Upon further review I think we should be using these tags for Azure Container App profile billing. And if we can do it from the agent side then other runtimes can have the same behavior.

Hey @duncanpharvey, thanks for surfacing this – indeed significantly looking – distinction between Azure App Services and Azure Container Apps. I do think this PR is still valid, as it does fill a feature gap – with it, Node.js profiler will be at parity with libdatadog in Azure App Services support. I agree that we might need to separately support (and hopefully in the agent) the Azure Container Apps use case.

That makes sense! I see that the Azure App Services metadata is already added in the Java and .NET Tracers so to be consistent it should be here as well. Azure Container App metadata can be handled in a separate PR.

LGTM!
