Saving System Information to a Log File
With the log file feature enabled, the log information generated by system can be saved to a
specified directory with a predefined frequency. This allows you to check the operation history
at any time to ensure that the device functions properly.
Logs are saved into the logfile buffer before they are saved into a log file. The system writes the
logs in the logfile buffer into the log file at a specified frequency, which is usually set to 24 hours
and during a relatively free time, in mornings for example. You can also manually save the logs.
After the logs in the logfile buffer are saved into the log file successfully, the system clears the
logfile buffer.
Follow these steps to set to save system information to a log file:
