# Tracing file rotation

OneSpan Authentication Server can be configured to automatically start a new trace file, based on one of the following:

- Size of the current trace file
- Number of days that the current trace file has been in use

| Trace-Rotate-Compress | Boolean | Enables or disables the compression of trace files once they are finished. |
| Trace-Rotate-Count | Integer | The number of trace files to keep. Includes archived and current trace files. |
| Trace-Rotate-Type | String | Specifies which factor the file rotation is based on. Possible values: - Size - Days |
| Trace-Rotate-Days | Integer | If Trace-Rotate-Type is set to Days, this specifies the number of days to use the current trace file before creating a new trace file. |
