+## Configurable SageMaker Environment Variables
+The following environment variables can be set on a SageMaker Model or Transform Job if further configuration is required:

+[Configures](https://docs.gunicorn.org/en/stable/settings.html#loglevel)
+the logging level for Gunicorn.
+```bash
+# Defaults to "info"

 ## Deploying to Multi-Model Endpoint
 
 SageMaker TensorFlow Serving container (version 1.5.0 and 2.1.0, CPU) now supports Multi-Model Endpoint. With this feature, you can deploy different models (not just different versions of a model) to a single endpoint.
