@artursouza @cicoyle please review. This is the first step to demonstrate OTEL with local development.

@salaboy I have checked the changes and I have a few general suggestions:

• Add a marker interface named ConfigurationSpec - this would allow us to mark all the other configuration with this interface, so it is easily discoverable in an IDE.
• Add a configuration spec builder - it is easier to follow what we try to put in a configuration spec if we use a builder approach. Having classes with constructors that have multiple parameters is not very user friendly. I would use something like the DaprContainer approach where you have with... which allows you to add different options.

Let me know your thoughts.

@artur-ciocanu I agree, but let's do this in two separate steps.. the Configuration class first and then we can add the fluent buileres to it. I am building an example where I want to test if this configurations work or not and based on that I want to make sure that the experience is polished with builders and all.

Regarding the ConfigurationSpec interface.. i don't think it makes sense.. if we just have a single configuration CRD that covers a bunch of different topics -> https://docs.dapr.io/operations/configuration/configuration-overview/ Maybe I am missing something

@salaboy thanks for feedback, my proposal was to have an interface that would allow us to model different configuration sections. It can be an interface named ConfigurationSpec or ConfigurationSection or ConfigurationParameters. Then we can have different implementations for different sections like:

• TracingConfigurationSection
• MetricsConfigurationSection
• LoggingConfigurationSection
• MiddlewareConfigurationSection
• etc

Let me know your thoughts.

@salaboy if it is not too much to ask, could you please rebase your branch. It is outdated.

@salaboy I was looking at the latest changes you pushed, the ones related to Observation API. In my opinion it would be easier to review if we have the following:

• One PR for OTEL configs for Dapr Testcontainer
• Second PR for Micrometer Observation API support for new Dapr Spring Boot integration

Let me know your thoughts.

I made good progress here.. now traces are propagated in some way for messaging, we need to do the same for the kvstore + bindings but the messaging side of things should show us the way forward.
If you look at this line : https://github.com/dapr/java-sdk/pull/1126/files#diff-f86931381933e4ae24b3f860afc7618f23aecb516cea8bfd0ce627b16bf64e19R159 this is propagating the trace parent to the grpc call @jonatan-ivanov @onobc but the sequencing might be wrong, as the spans are parallel and not one inside the other as shown in this screenshot:

Here is the node graph:

In theory, we should see "Rest Endpoint -> Messaging template bean -> GRPC call to the Dapr Sidecar", but at least now the traceparent is propagated and all the spans belong to the same traceparent.

@artur-ciocanu I will appreciate any help that you can provide here.. I am happy for you to copy the contents of this PR in separate PRs if you think that is best, I will be away until the 13th of October so any help on moving this forward will be highly appreciated.

@artur-ciocanu I can close this one right?

@artur-ciocanu I can close this one right?

I think so

[artur-ciocanu]

@salaboy could you please close this PR and we could focus on other observation enhancements.
