Adding Span

...
from opentelemetry import trace
tracer = trace.get_tracer(__name__)

def ingest_metrics(metrics: list):
    with tracer.start_as_current_span("ingest_metrics"):
        logger.info("Ingesting Metrics")
        ...

Visualizing Traces

By sending opentelemetry data to a backend like Jaeger or Tempo, you can visualize the traces and spans
