2. Click on “App Service logs” under the Monitoring section in the left-hand menu.
3. Toggle the “Application Logging (Filesystem)” switch to “On”.
4. Choose the desired log level (e.g. Information, Error, Warning) from the drop-down menu.
5. Choose the desired retention period for the logs.
6. Choose the destination for the logs (either a file system on the web app’s instance or a storage account).
7. Click “Save” to apply the changes.

Web Server Logging Enablement

1. Navigate to the “Diagnostic logs” tab under the “Monitoring” section in the left-hand menu.
