Great suggestion splitting off the tests. You could also use https://github.com/open-telemetry/opentelemetry-java-contrib/blob/main/maven-extension/README.md I create a var on Jenkins with -Dotel.traces.exporter=otlp -Dmaven.ext.class.path=c:/opt/opentelemetry-maven-extension-1.10.0-20220113.055723-2.jar -Dotel.service.name=maven -Dotel.instrumentation.maven.mojo.enabled=false and tack it onto my build commands. There's an OpenTelemetry plugin for Jenkins so I can get to the results on Jaeger for all past builds without having to retain the workspace. Delany
