stdouttrace exporter

[pellared]

We should add support for setting/enabling stdouttrace exporter.

This is very helpful during troubleshooting and debugging.

We might consider to add a dedicated env var to set it as there is "known value" defined by the specification. E.g. OTEL_GO_AUTO_TRACES_STDOUT_EXPORTER_ENABLED.

Would be happy to take this one on. What do you think of using the OTEL_TRACES_EXPORTER=console environment variable for this? See open-telemetry/opentelemetry-specification#3742

I made the comment before seeing @MrAlias's PR, it looks like that would allow any exporter available through the auto package?

Correct. Still the comment is valuable.
