I am trying to setup tracing in a quickstart Helidon MP project following the student guide instructions.

I have a windows 11 machine.

I have completed the steps but jaeger search is neither showing Service helidon-greet nor any tracing information.

Please help!

Steps done 0. Created the project using Helidon version 3.2.1 CLI for windows https://helidon.io/docs/v3/#/about/cli

  1. Install and run jaeger-1.46.0-windows-amd64
  2. Add in pom.xml
    <dependency>
       <groupId>io.helidon.tracing</groupId>
       <artifactId>helidon-tracing-jaeger</artifactId>
       <scope>runtime</scope>
    </dependency>
  1. Added following lines in microprofile-config.properties
    tracing.service=helidon-greet
    tracing.sampler-type=const
    tracing.sampler-param=1
  1. Build
mvn clean package
java -jar target/helidon-mp.jar
engineersunit

This was resolved by the poster himself, hence adding his solution here:

I am using Helidon version 3.2.1 and therefore there may be difference in the tracing OOTB integration with Jaeger which now has moved to OpenTelemetry as per MicroProfile 6.0 specifications. I have resolved the issue by adding more properties int the config as per https://helidon.io/docs/v3/#/mp/tracing#jaeger-tracing:

tracing.service=helidon-greet
tracing.sampler-type=const
tracing.sampler-param=1

# added more config fields
tracing.enabled=true
tracing.protocol=http
tracing.host=localhost
tracing.port=14250
