Steps to reproduce
Logs are not being sent or exported to an OTEL collector.
With this OTEL configuration:
receivers:
otlp:
protocols:
grpc:
processors:
batch:
exporters:
logging:
service:
pipelines:
logs:
receivers: [otlp]
exporters: [logging]
And this Python code:
import logging
from opentelemetry._logs import set_logger_provider
from opentelemetry.exporter.otlp.proto.grpc._log_exporter import OTLPLogExporter
from opentelemetry.sdk._logs import LoggerProvider, LoggingHandler
from opentelemetry.sdk._logs.export import (
BatchLogRecordProcessor,
SimpleLogRecordProcessor,
ConsoleLogExporter
)
from opentelemetry.sdk.resources import Resource
logger_provider = LoggerProvider(
resource=Resource.create(
{
"service.name": "my-dummy-service",
"service.instance.id": "my-first-instance",
}
)
)
set_logger_provider(logger_provider)
exporter = OTLPLogExporter(insecure=True)
#exporter = ConsoleLogExporter()
logger_provider.add_log_record_processor(BatchLogRecordProcessor(exporter))
#logger_provider.add_log_record_processor(SimpleLogRecordProcessor(exporter))
handler = LoggingHandler(level=logging.NOTSET, logger_provider=logger_provider)
# Attach OTLP handler
# TODO: adding handler to root does nothing or it is not reflected in the container
#logging.getLogger().addHandler(handler)
#logging.info("When you want to see some important info...")
#logging.error("There is an unexpected error...")
# Using a custom logger:
my_logger = logging.getLogger("my-dummy-service-logger")
my_logger.addHandler(handler)
my_logger.info("When you want to see some important info...")
my_logger.error("There is an unexpected error...")
The output is this:
Failed to export logs to localhost:4317, error code: StatusCode.UNIMPLEMENTED
What is the expected behavior?
I was expecting that the logs would be sent to the OTEL collector and then I would be able to visualize that information from the OTEL container, but that is not happening.
What is the actual behavior?
When using the root logger, it does nothing: console output is empty and nothing is reflected in OTEL container logs.
When using a custom or namespaced logger, console output shows this error: Failed to export logs to localhost:4317, error code: StatusCode.UNIMPLEMENTED
Additional context
I have used these links as reference for this dummy code https://opentelemetry-python.readthedocs.io/en/latest/examples/logs/README.html and https://github.com/open-telemetry/opentelemetry-python/tree/main/docs/examples/logs, but I cannot achieve the expected result.
I'm not able to reproduce this. Running the script with the list of requirements and a local collector (latest main, using the above config) works fine for me. I can only get the above error if I run the script without the collector.

Are you still experiencing this issue?
@lzchen, I just checked it again using version 1.25.0, and it doesn't happen anymore, I don't know if it is due to the recent version, or to the new version of the OTEL collector, but issue does not happen anymore.
