Get Current Tracer
Let’s explore how to work with tracers - the core components for span creation in OpenTelemetry.from opentelemetry import trace
# Assuming SpanAttributes, FiSpanKindValues, ToolCallAttributes,
# function_call_name, and arguments variables are defined externally.
tracer = trace.get_tracer(__name__)
# Start a new span for the tool function handling
with tracer.start_as_current_span("HandleFunctionCall", attributes={
SpanAttributes.FI_SPAN_KIND: FiSpanKindValues.TOOL.value,
ToolCallAttributes.TOOL_CALL_FUNCTION_NAME: function_call_name,
ToolCallAttributes.TOOL_CALL_FUNCTION_ARGUMENTS_JSON: str(arguments),
SpanAttributes.INPUT_VALUE: function_call_name
}) as span:
pass
