-### Logging to a Rotating File
-
-#### Enabling Rotating File Logging
-
-To enable audit logging to a rotating file, set the following in your configuration (this feature is disabled by default):
-
-```yaml
-auditLog:
-  rotateFile:
-    enabled: true
-```
-
-With this configuration, the default behavior is:
-
-- Rotate logs at midnight (local system timezone)
-- Log file format: redhat-developer-hub-audit-%DATE%.log
-- Log files stored in /var/log/redhat-developer-hub/audit
-- No automatic log file deletion
-- No gzip compression of archived logs
-- No file size limit
-
-#### Customizing Log File Location and Name
-
-To change the directory where log files are stored, specify a custom path (an absolute path is recommended): By default, the audit logs are written in the `/var/log/redhat-developer-hub/audit` directory.
-
-```yaml
-auditLog:
-  rotateFile:
-    logFileDirPath: /custom-path
-```
-
----
-
-**NOTE**
-
-The specified directory will be created automatically if it does not exist.
-
----
-
-By default, the audit log files will be in the following format: `redhat-developer-hub-audit-%DATE%.log` where `%DATE%` is the format specified in [`auditLog.rotateFile.dateFormat`](#configuring-file-retention-policy).
-
-To customize the log file name format, use:
-
-```yaml
-auditLog:
-  rotateFile:
-    logFileName: custom-audit-log-%DATE%.log
-```
-
-#### Configuring File Rotation Frequency
-
-The default file rotation occurs daily at 00:00 local time. You can adjust the rotation frequency with the following configurations:
-
-```yaml
-auditLog:
-  rotateFile:
-    frequency: '12h' # Default: `custom`
-    dateFormat: 'YYYY-MM-DD' # Default: `YYYY-MM-DD`
-    utc: false # Default: `false`
-    maxSize: 100m # Default: undefined
-```
-
-`frequency` options include:
-
-- `daily`: Rotate daily at 00:00 local time
-- `Xm`: Rotate every X minutes (where X is a number between 0 and 59)
-- `Xh`: Rotate every X hours (where X is a number between 0 and 23)
-- `test`: Rotate every 1 minute
-- `custom`: Use `dateFormat` to set the rotation frequency (default if frequency is not specified)
-
----
-
-**NOTE**
-If `frequency` is set to `Xh`, `Xm` or `test`, the `dateFormat` setting must be configured in a format that includes the specified time component. Otherwise, the rotation will not work as expected.
-
-For example, `dateFormat: 'YYYY-MM-DD-HH'` for hourly rotation. `dateFormat: 'YYYY-MM-DD-HH-mm'` for minute rotation.
-
----
-
-Examples:
-
-```yaml
-auditLog:
-  rotateFile:
-    # If you want to rotate the file every 17 minutes
-    dateFormat: 'YYYY-MM-DD-HH-mm'
-    frequency: '17m'
-```
-
-The `dateFormat` setting configures both the %DATE% in logFileName and the file rotation frequency if frequency is set to `custom`. The default format is `YYYY-MM-DD`, meaning daily rotation. Supported values are based on [Moment.js formats](https://momentjs.com/docs/#/displaying/format/).
-
-If `frequency` is set to `custom`, then rotations will take place when the date string, represented in the specified `dateFormat`, changes.
-
-Examples:
-
-```yaml
-auditLog:
-  rotateFile:
-    # If you want rotations to occur every week for some reason and at the start of each month. Example `%DATE$` = '2025-Jul-Week 30'
-    dateFormat: 'YYYY-MMM-[Week] ww'
-```
-
-```yaml
-auditLog:
-  rotateFile:
-    # If you want to rotate the file at noon and midnight
-    dateFormat: 'YYYY-MM-DD-A'
-```
-
-To use UTC time for `dateFormat` instead of local time:
-
-```yaml
-auditLog:
-  rotateFile:
-    utc: true # Default: False
-```
-
-To set a maximum log file size before rotation (which would add a count suffix to the filename upon reaching the size limit): Ex: `redhat-developer-hub-audit-2024-07-22.log.3`.
-
-To configure `maxSize`, provide a number followed by one of `k`, `m`, or `g` to specify the file size in kilobytes, megabytes, or gigabytes. No `maxSize` is configured by default.
-
-```yaml
-auditLog:
-  rotateFile:
-    maxSize: 100m # Sets a max file size limit of 100MB for audit log
-```
-
-#### Configuring File Retention Policy
-
-By default, log files are not deleted or archived. You can configure the maximum number of files to keep:
-
-```yaml
-auditLog:
-  rotateFile:
-    maxFilesOrDays: 14 # Deletes the oldest log when there are more than 14 log files
-```
-
-Or, configure the maximum number of days to retain logs by appending:
-
-```yaml
-auditLog:
-  rotateFile:
-    maxFilesOrDays: 5d # Deletes logs older than 5 days
-```
-
----
-
-**NOTE**
-
-If log deletion is enabled, a `.<sha256 hash>-audit.json` will be generated in the directory where the logs are to track generated logs. Any log file not contained in it will not be subject to automatic deletion.
-
-Currently, a new `.<sha256 hash>-audit.json` file is generated every time the backend is started. This means old audit logs will no longer be tracked/deleted with the exception of any log files reused by the current backend.
-
----
-
-To archive and compress rotated logs using gzip:
-
-```yaml
-auditLog:
-  rotateFile:
-    zippedArchive: true # Default: false
-```
