Sultan Zhantemirov created WFLY-12842: ----------------------------------------- Summary: MicroProfile Config properties are not taken into account by Jaeger client Key: WFLY-12842 URL: https://issues.jboss.org/browse/WFLY-12842 Project: WildFly Issue Type: Bug Components: MP OpenTracing Affects Versions: 18.0.1.Final Reporter: Sultan Zhantemirov Assignee: Emmanuel Hugonnet I am trying to migrate tests from [Thorntail|https://github.com/rhoar-qe/thorntail-test-suite/tree/master/mi...] test suite, both MP OpenTracing 1.0 and 1.3. Let's have a simple Arquillian test with Jaeger containerized in Docker and a WAR-archive with CDI enabled (_beans.xml_) and _META-INF/microprofile-config.properties_ included: {noformat} jaeger.sampler.param=1 jaeger.sampler.type=const {noformat} But it seems that Jaeger instance running in Docker does not take into account the properties defined in WAR's _microprofile-config.properties_ file. It should trace every request to the deployed application but as far as I can see it does not. Only manual instantiation and configuration of a Tracer object in @ApplicationScoped service leads to the expected behaviour. With @Inject 'ed tracer there is no success. Regarding that let's imagine a user case: we have a deployment with _@Traced_ annotated classes/methods, CDI enabled (_beans.xml_) and _META-INF/microprofile-config.properties_ entries for Jaeger configuration. We don't want to modify existing classes (configuring existing tracer instance), we only want trace each REST request. -- This message was sent by Atlassian Jira (v7.13.8#713008)
