Opentelemetry: javaagent jaeger exporter - add header

Question

I have a problem with jaeger exporter, I have been looking for a solution for a long time and I understand that the solution is either not there or it has not been done yet.

Is this at all possible to solve somehow? How to add header to jaeger exporter?

I am using javaagent and jaeger exporter. I want to add a header to the grpc request.

The documentation states that I can only configure 3 environment variables for the jaeger exporter. https://github.com/open-telemetry/opentelemetry-java/blob/main/sdk-extensions/autoconfigure/README.md#jaeger-exporter

I can insert headers only if I use OTEL exporter(OTEL_EXPORTER_OTLP_HEADERS).

Accordingly, jaeger exporter ignores this variable. -> OTEL_EXPORTER_OTLP_HEADERS

Thanks.

What about using Opentelemetry Collector to do this?

You can use the javaagent to forward to Opentelemetry Collector, which allows you to use OTEL_EXPORTER_OTLP_HEADERS.

Then, in turn, the collector can forward traces to your Jaeger instance
