"""
Examples to show usage of the azure-core-tracing-opentelemetry
with the Eventhub SDK.
This example traces calls for sending a batch to eventhub.
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.
