Hi,

I would like to able to configure the microprofile-opentracing-smallrye extension in wildfly 19 with substituted variables (environment or system).
When I try this it seems the values are not resolved, for example

<subsystem xmlns="urn:wildfly:microprofile-opentracing-smallrye:2.0" default-tracer="jaeger">
    <jaeger-tracer name="jaeger">
        <tags>
            <property name="env" value="${env.ENV}"/>
            <property name="user" value="joe"/>
        </tags>
        <sampler-configuration sampler-type="ratelimiting" sampler-param="1.0"/>
        <sender-configuration sender-endpoint="http://${JAEGER_AGENT_HOST}:14268/api/traces"/>
    </jaeger-tracer>
</subsystem>

results in:

2020-03-29 15:17:49,448 ERROR [jaeger.RemoteReporter-QueueProcessor] [] [] [] [] [] (io.jaegertracing.internal.reporters

is this supported ?

Thanks,
Joe

Hey,

this attribute doesn't support expressions.

But it could probably be changed to support it, best to create jira issue for that.
