src/SIL.Machine.AspNetCore/SIL.Machine.AspNetCore.csproj line 37 at r1 (raw file):

		<PackageReference Include="Microsoft.AspNetCore.Mvc.NewtonsoftJson" Version="6.0.16" />
		<PackageReference Include="Microsoft.Extensions.Http.Polly" Version="6.0.14" />
		<PackageReference Include="OpenTelemetry.Exporter.Console" Version="1.6.0" />

I would move these package references to the individual server projects, since this project has no dependency on OpenTelemetry.

            .AddHttpClientInstrumentation()
            .AddGrpcClientInstrumentation()
            .AddSource("MongoDB.Driver.Core.Extensions.DiagnosticSources")

Doesn't this need a subscription to the mongo DB - or do I nut understand: https://github.com/jbogard/MongoDB.Driver.Core.Extensions.DiagnosticSources?

You are correct. I've already added that in Serval (see the other PR). And Machine calls that code here. (And I can verify that it works locally; I'm getting appropriate traces from MongoDB in all containers).

@johnml1135 Do you want this to be merged or would you rather I put the console exporter behind a development flag first?

[johnml1135]

Please do - I don't want it spamming production logging.

@johnml1135 I hadn't yet added that. I'll make another PR I guess. I'm sorry - I just got out of a long meeting.
