"""
Examples to show usage of the azure-core-tracing-opentelemetry
with the storage SDK.
This example traces calls for creating a container in storage and exports it
using the ConsoleSpanExporter.
An alternative path to export using the OpenTelemetry exporter for Azure Monitor
is also mentioned in the sample. Please take a look at the commented code.
