## Standard logging configuration
The default logging configuration for Azure Web Apps in an environment in DXP has the following settings:
**Application logging** is _enabled_, with level _Error_, and logs are stored in the BLOB storage with _90 days retention_.
**Web server logging** is _enabled_, and logs are stored in the BLOB storage with _90 days retention_.
**Detailed error messages** are _disabled_.
**Failed request tracing** is _disabled_.
You can access application logs for environments from the [DXP Self-Deployment Guide](🔗), either as a live stream or downloaded for offline analysis.
The configuration above is applied to environments during provisioning and the customer can change it for the **Integration** environment. Contact [customer support](🔗) to change any of the following for **Preproduction** or **Production** environments:
Get access to web server logs.
Temporarily change logging level.
Temporarily enable detailed error messages.
Temporarily enable failed request tracing.
## Implementing logging for your application
You should use the Optimizely logging abstraction, as described in [Logging into .Net Diagnostics Trace]([https://docs.developers.optimizely.com/content-cloud/v11.0.0-content-cloud/docs/logging-into-net-diagnostics-trace-legacy"CMS](🔗) Developer Guide").
In a DXP environment the logger factory is set to EPiServer.Logging.TraceLoggerFactory, so all application log messages are stored in the BLOB storage.
