Multiple services

Question

I have multiple services in a various assemblies and I’d like to be able to track each one by name

In the code below, there is the option to call AddService multiple times but I cannot see how to get a mapping from that to a service specific ActivitySource
Startup .SetResourceBuilder(ResourceBuilder.CreateDefault().AddService(info.name)

E.g. Lets say I have a UserService and a Repository<User> service
I’d like to add add a services UserService and Repository_User and then in my UserService I’d have an ActivitySource named UserService and in Repository<User> I’d have an ActivitySource named Repository_User

Is this configuration possible?

I’m using Jaeger exporter if it makes a difference

Would it be something like this:

var openTelemetry = Sdk.CreateTracerProviderBuilder()
                    .AddSource("Samples.SampleClient", "Samples.SampleServer")
                    .SetResourceBuilder(ResourceBuilder.CreateDefault().AddService("otlp-test"))
                    .AddOtlpExporter(opt => opt.Endpoint = new Uri(endpoint))
                    .Build();

I use this pattern currently, and it has the downside of every operation being grouped / tagged under the service otlp-test, instead of (e.g. Samples.SampleClient, Samples.SampleServer).

If I add multiple services(…AddService(“Service1”).AddService(“Service2”), it appears that the last one wins, e.g. everything is grouped under that name.

I cannot find a way to map a service name back to a source, in my desired state it is a 1=1 mapping.

I think the .NET implementation (at least) is assuming that a process is a service, whereas what I want is the ability to separate my process into multiple logical services.

Using Jaeger at least, logically separating services has the benefit of colour coding each service which makes it easy to visually distinguish logical components of a larger application. Maybe a picture helps 😃

@AlexGS74 you can disregard the prior questions it looks like I just configure the AspNetCoreInstrumentation to filter out requests from other services and that solves that riddle. Now I just need to ping my main man Jimmy Bogard and see if we can get a similar filter setup for the NServiceBus side for my worker process and this problem will be solved for good. Many thanks for pointing me in the right direction!
