Is it possible to use Loguru with OpenTelemetry Logging Instrumentation? #674
Description
I'm trying to configure Loguru with OpenTelemetry Logging Instrumentation, but I'm not getting. I can see that LoggingInstrumentor().instrument() get the default factory of loggin and than add some controls, changing the default factory of logging. I'm not able to find a way to define the factory for Loguru.
Block the code executed by LoggingInstrumentor().instrument()
def _instrument(self, **kwargs):
provider = kwargs.get("tracer_provider", None) or get_tracer_provider()
old_factory = logging.getLogRecordFactory()
LoggingInstrumentor._old_factory = old_factory
service_name = None
def record_factory(*args, **kwargs):
record = old_factory(*args, **kwargs)
record.otelSpanID = "0"
record.otelTraceID = "0"
nonlocal service_name
if service_name is None:
resource = getattr(provider, "resource", None)
if resource:
service_name = (
resource.attributes.get("service.name") or ""
)
else:
service_name = ""
record.otelServiceName = service_name
span = get_current_span()
if span != INVALID_SPAN:
ctx = span.get_span_context()
if ctx != INVALID_SPAN_CONTEXT:
record.otelSpanID = format(ctx.span_id, "016x")
record.otelTraceID = format(ctx.trace_id, "032x")
return record
logging.setLogRecordFactory(record_factory)
set_logging_format = kwargs.get(
"set_logging_format",
environ.get(OTEL_PYTHON_LOG_CORRELATION, "false").lower()
== "true",
)
if set_logging_format:
log_format = kwargs.get(
"logging_format", environ.get(OTEL_PYTHON_LOG_FORMAT, None)
)
log_format = log_format or DEFAULT_LOGGING_FORMAT
log_level = kwargs.get(
"log_level", LEVELS.get(environ.get(OTEL_PYTHON_LOG_LEVEL))
)
log_level = log_level or logging.INFO
logging.basicConfig(format=log_format, level=log_level)
