The default logging configuration for Azure Web Apps in an environment in DXP has the following settings:

- **Application logging** is turned on, with level *Error*, and logs are stored in the BLOB storage with *90 days retention*.
- **Web server logging** is turned on, and logs are stored in the BLOB storage with *90 days retention*.
- **Detailed error messages** are turned off.
- **Failed request tracing** is turned off.

You can access application logs for environments from the [DXP self-service](docId\:jsjQEdJu2vU33eXzlbTzz) as a live stream or download them for offline analysis.

The configuration above is applied to environments during provisioning, and the customer can change it to the Integration environment. Contact [Support](mailto\:support@optimizely.com) to change any of the following for Preproduction or Production environments:

- Get access to web server logs.
- Temporarily change the logging level.
- Temporarily enable detailed error messages.
- Temporarily enable failed request tracing.

You should use the Optimizely logging abstraction described in [Log into .Net Diagnostics Trace](docId\:v2tzNKe6zQLSdJ_lny5UQ).

In a DXP environment, the logger factory is set to `EPiServer.Logging.TraceLoggerFactory`, so application log messages are stored in the BLOB storage.
