The otel::tracing log level is not set to the same or lower level than TRACING_LEVEL, which makes span.set_parent() invalid.

Cargo.toml

axum = "0.7"

The span generated before setting will not bring in the traceparent id of the http request: After configuring the tagger log level, it can be normally associated with the incoming trace:

I release a new version of axum-tracing-opentelemetry with the missing feature flag "tracing_level_info".

Bad new, this version is for opentelemetry 0.24 and the auto-bump version releases axum-tracing-opentelemetry with version 0.19.1

My tracing otlp tonic export setup works pretty fine but tonic-tracing-opentelemetry = { version = "0.20.0", features = ["tracing_level_info"] } is not exporting / producing anything to my otel backend (jaeger).

For other things I use tracing-opentelemetry = "0.25.0"

My overcall tracing level is INFO. I tried with and without ["tracing_level_info"] so I don't really know what's going on.

opentelemetry use static variables, you should not have multiple version of opentelemetry (else tracer could not be connected to your configured exporter,...)

# Check only one version of opentelemetry_api should be used
# else issue with setup of global (static variable)
# check_single_version_opentelemtry:
cargo tree -i opentelemetry_api

Before using this crate I have no results for cargo tree -i opentelemetry_api.

For cargo tree -i opentelemetry_sdk I get
