opentelemetry-javaagent exporter=zipkin does not work on version 2.5.0 #11783

Closed donniexyz closed 2 months ago

donniexyz commented 2 months ago

Describe the bug

When using opentelemetry-javaagent.jar version 2.5.0 with -Dotel.traces.exporter=zipkin the exporter seems ignored and still attempt to connect to port 4318. Setting via OTEL_TRACES_EXPORTER environment property also has same behavior. opentelemetry-javaagent.jar version 1.33.4 works as expected.

Steps to reproduce

Launch java application with javaagent: opentelemetry-javaagent v2.5.0

D:\apps\jdk\jdk-21\bin\java.exe -javaagent:D:/java/exec/opentelemetry-javaagent-v2.5.0.jar ^
   -Dotel.service.name=dongo ^
   -Dotel.traces.exporter=zipkin ^
   -Dotel.metrics.exporter=none ^
   -Dotel.exporter.zipkin.endpoint=http://localhost:9411/api/v2/spans ^
   -jar target\med-spring-boot-demo-0.0.1-SNAPSHOT.jar

Expected behavior

Using version 1.x WORKS: opentelemetry-javaagent v1.33.4

D:\apps\jdk\jdk-21\bin\java.exe -javaagent:D:/java/exec/opentelemetry-javaagent-v1.33.4.jar ^
   -Dotel.service.name=dongo ^
   -Dotel.traces.exporter=zipkin ^
   -Dotel.metrics.exporter=none ^
   -Dotel.exporter.zipkin.endpoint=http://localhost:9411/api/v2/spans ^
   -jar target\med-spring-boot-demo-0.0.1-SNAPSHOT.jar

Actual behavior

If you look closely at the error message you'll see Failed to export logs. 2.x version enables logs exporter by default, if you don't wish to export logs you can disable it the same way as you disable the metrics exporter with -Dotel.logs.exporter=none

Thanks, it works after adding -Dotel.logs.exporter=none.

Looks like this got figured out. 🥳 Please feel free to reopen if this is not the case.
