The MicroProfile OpenTracing specification provides a mechanism to access an opentracing.io Tracer.
To enable the MicroProfile OpenTracing 1.0 feature, add the following element declaration inside the featureManager element in your server.xml file:
<feature>mpOpenTracing-1.0</feature>
If you are developing a feature that depends on the MicroProfile OpenTracing 1.0 feature, include the following item in the Subsystem-Content header in the feature manifest file for your new feature:
com.ibm.websphere.appserver.mpOpenTracing-1.0; type="osgi.subsystem.feature"
