@Prashant Shahi I am unable to see logs , though I can see services and traces successfully

Logs of the containers in K8s cluster where signoz is installed is captured by

k8s-infra

chart.

Not all languages support OTEL logs SDK, right now python and Java are supported. If they are using a different language they will have to deploy the collector on the application instance.

Logging is not enable by default for some reason (more context https://github.com/open-telemetry/opentelemetry-python/issues/2594). You can enable it by setting

OTEL_PYTHON_LOGGING_AUTO_INSTRUMENTATION_ENABLED=true

but make sure you understand the potential issue with it from the linked issue.

I have done

logging.basicConfig(level=<http://logging.INFO|logging.INFO>, force=True)  # Should happen before any logging

app = FastAPI(**opts)
app.add_middleware(LoggingMiddleware)

class LoggingMiddleware(BaseHTTPMiddleware):
    async def dispatch(self, request: Request, call_next):
        # Record the actual processing time for the request
        start_time = time.time()
        try:
            response = await call_next(request)
            response_status_code = response.status_code
            stats_json = get_stats_json(start_time, request, response_status_code)
        except ClientDisconnect:
            # We don't want to handle this and logs get cluttered
            stats_json = get_stats_json(start_time, request, status.HTTP_418_IM_A_TEAPOT)
            stats_json["error_reason"] = "ClientDisconnect"
            <http://logger.info|logger.info>(stats_json)
            response = JSONResponse(stats_json, status.HTTP_418_IM_A_TEAPOT)
        except Exception as ex:
            # Since this was unexpected exception
            stats_json = get_stats_json(start_time, request, status.HTTP_500_INTERNAL_SERVER_ERROR)
            json_response_body = {"detail": repr(ex)}
            response = JSONResponse(json_response_body, status.HTTP_500_INTERNAL_SERVER_ERROR)
            logger.error(json_response_body, exc_info=True)
        if request.url.path != "/":
            <http://logger.info|logger.info>(stats_json)
        return response

And udpated the environment variable as you said but I still don't see the logs beta getting populated

Remove this and let me know if works

logging.basicConfig(level=<http://logging.INFO|logging.INFO>, force=True)

ok

When you

force=True

it removes handler what’s automatically configure by

opentelemetry-instrument

. And any calls after that with

logging.basicConfig

will not be affective. That’s problem we are talking about here https://github.com/open-telemetry/opentelemetry-python/issues/2594#issuecomment-1099620061.

Okay it works on my docker signoz but it doesn't send logs on my jubernetes signoz

@Abhinav Ramana are you using

OTLPHandler + OTLPLogExporter

or something else?

not sure, but nothing special we use I believe

Sure
