How does jaeger authentication work in auto instrumentation .

[vinitaaher]

Hi All,
I did auto instrumentation in java for my app and export the traces to jaeger. Following is the parameters I am passing to jvm and it is working.
java -javaagent:tracinglib/opentelemetry-javaagent-all.jar
-Dotel.exporter=jaeger
-Dotel.exporter.jaeger.service.name=adService
-Dotel.exporter.jaeger.endpoint=localhost:14250
-jar build/libs/hipstershop-0.1.0-SNAPSHOT-fat.jar
But now I want do Jaeger authentication using either bearer token or username and password.
Please suggest how to do this.I have bearer token as well username and password also but I don't understand how to pass it with above JVM parameters.

Hi @vinitaaher - we currently don't support custom authentication of exporters in OpenTelemetry. This is an important feature so I've opened up an issue in the general specification for guidance on how to enable this. Sorry for the trouble

open-telemetry/opentelemetry-specification#1344

Thank You @anuraaga

Is it available now. they're saying you can implement extensions to enable authentication and pass the bearer token in otel.exporter.otlp.headers. Do we have any reference on how to do it?

It is not available by default as a part of the package - and it won't be until it is present in the OTel specification.
There is a possibility to implement that as a custom javaagent extension, but that your (javaagent user) custom work.
