+Other OpenTelemetry Instrumentations are available [here](https://github.com/open-telemetry/opentelemetry-python-contrib/tree/main/instrumentation) and can be used in addition to `configure_azure_monitor`. Here is an example for adding the SQLAlchemy Instrumentation.

+from opentelemetry.instrumentation.sqlalchemy import SQLAlchemyInstrumentor
+from sqlalchemy import create_engine, text

+# SQLAlchemy instrumentation is not officially supported by this package
+# However, you can use the OpenTelemetry instument method manually in
+# conjunction with configure_azure_monitor
+SQLAlchemyInstrumentor().instrument(
+    engine=engine,

+# Database calls using the SqlAlchemy library will be automatically captured
