Describe your environment

OS: Debian 12
Python version: 3.13
SDK version: 1.28.2
API version: 0.49b2

What happened?

Warnings and significant delay at the startup:

Overriding of current EventLoggerProvider is not allowed

opentelemetry-python/opentelemetry-api/src/opentelemetry/_events/__init__.py

Lines 196 to 198 in db4ef06

    
           _logger.warning( 
        
               "Overriding of current EventLoggerProvider is not allowed" 
        
           )

Timeout was exceeded in force_flush().

opentelemetry-python/opentelemetry-sdk/src/opentelemetry/sdk/_logs/_internal/export/__init__.py

Lines 376 to 377 in db4ef06

    
           if not ret: 
        
               _logger.warning("Timeout was exceeded in force_flush().")

Steps to Reproduce

pip install opentelemetry-distro[otlp] opentelemetry-instrumentation
opentelemetry-bootstrap -a install

OTEL_LOGS_EXPORTER=console,otlp
OTEL_PYTHON_LOGGING_AUTO_INSTRUMENTATION_ENABLED=true

Expected Result

No warnings

Actual Result

Warnings and delay

Additional context

Probalby regression in 0.49b2 version
#4270

Would you like to implement a fix?

None

What does "significant delay at startup" mean? The warning is harmless and has already been fixed in #4299

aborigeth · 2024-12-02T08:25:04Z

What does "significant delay at startup" mean?

About 30 seconds till application starts

aborigeth · 2024-12-03T14:25:23Z

Timeout was exceeded in force_flush(). happens due to uvicorn, otherwise it works fine.

@aborigeth

Seems like the error message Overriding of current EventLoggerProvider is not allowed might not be related to the delay in application start.

Could you paste a code snippet of what you are instrumenting?

aborigeth · 2024-12-04T08:09:30Z

Yes, delay caused by something else, maybe fastapi/uvicorn implementation.

Could you paste a code snippet of what you are instrumenting?

@aborigeth How you are exporting logs? It looks like you setup to send otlp and console but the otlp receiver is not there?

@aborigeth How you are exporting logs? It looks like you setup to send otlp and console but the otlp receiver is not there?

OTEL_EXPORTER_OTLP_ENDPOINT="https://opentelemetry-collector.example.com"
OTEL_EXPORTER_OTLP_HEADERS="Authorization=Basic%20XXXX"

As I mentioned above, instrumentation and export works fine (apart from EventLoggerProvider warning) in regular Python application.
But when I start FastAPI with uvicorn - delay appears.

Following because I have the exact same issue.

@mats-ruell Which one?

OTEL_SERVICE_NAME='XXX'

OTEL_METRICS_EXPORTER='otlp'
OTEL_LOGS_EXPORTER='console,otlp'

Traces and metrics both work perfectly. I am not getting logs in either console or otlp endpoint. It is also a FastAPI application.
