Add tracing for microprofile-rest-client

[pavolloffay]

Add tracing for https://github.com/eclipse/microprofile-rest-client. Tracing metadata like tags/logs should be the same as for JAX-RS client.

We need to figure out how this cross-spec specification should be handled. Should it be added here or in microprofile-rest-client? I would vote to add it here.

A pointer to rest-client issue allowing tracing integration eclipse/microprofile-rest-client#35 (comment).

There has been some discussion in the past around spec integration and the need for a MP level spec to cover those interactions.

Doing so would also provide for a MP level TCK to verify such behavior

[pavolloffay]

Is there any timeline to add MP level spec?

My main concern about adding microprofile-rest-client here is that this spec shouldn't probably directly depend on the microprofile-rest-client. What if a vendor does not support mp-rest-client but it wants to use tracing only for jax-rs?

[kenfinnigan]

I don't think there is, but we can raise it again today

@pavolloffay It should be possible to add Open Tracing providers to the MP Rest Client with only a compile-time dependency on microprofile-rest-client. You would need the compile-time dependency in order to build the RestClientBuilderListener implementation class (which could then register the Open Tracing provider(s)), but that class would only be loaded by the MP Rest Client implementation at runtime - so there is no need for a runtime dependency.

Thorntail 2.3.0.Final documentation mentions this issue:

Currently, MicroProfile OpenTracing does not integrate with MicroProfile RestClient, so you need to use a pure JAX-RS Client. This limitation will be removed in the future, see MicroProfile OpenTracing issue #82.

Is there any opened issue on Thorntail for MP-Restclient + MP-Opentracing? It still not working on Thorntail 2.3.0.Final.

The test code is in this repo: https://github.com/redhat-developer-demos/microprofile-demo

Hi @rafabene, the OT spec supports tracing for MP rest client 1.2. Here is a PR for smallrye smallrye/smallrye-opentracing#28 - at the moment is blocked by not completed rest client implementation. Once smallrye impls are in place it will be used in throntail @kenfinnigan probably knows when that should be.

Hi @pavolloffay, I can see the PR is merged, does there is anything new about this request?

[pavolloffay]

@wutingbupt the support for MP rest client is supported since 1.2. What else is missing for you?

@pavolloffay I have tried this morning with the open tracing 1.3.

But I got something like this:

{"stackTrace":"java.lang.NoClassDefFoundError: Failed to link io/smallrye/opentracing/SmallRyeRestClientListener (Module \"io.smallrye.opentracing\" from BootModuleLoader@6bb4dd34 for finders [JDK Module Finder, BootstrapClasspathModuleFinder, BootstrapModuleFinder(org.wildfly.swarm.bootstrap), ClasspathModuleFinder, ContainerModuleFinder(swarm.container), ApplicationModuleFinder(thorntail.application), org.wildfly.swarm.bootstrap.modules.DynamicModuleFinder@7d9f158f])
I can see the dependency is well added, so I have no idea why it will complain about this .

Br,
Tim

@wutingbupt please report this issue in the implementation. This is not related to the specification. So please report this in Smallrye or thorntail depending how you are using it. A dependency tree would be helpful to investigate.

[wutingbupt]

Thanks very much, I will do that. Br, Tim Pavol Loffay <notifications@github.com> 于2019年4月15日周一 下午1:06写道：
