This feature enables the device to save generated log information to a log file. You can specify how often
the log file is saved, or you can manually save the log file.
Logs are saved into the log file buffer. The system writes the logs from the log file buffer to the log file at
the specified interval (24 hours by default). You can also manually save the logs while the device is not
busy. After saving logs from the log file buffer to the log file, the system clears the log file buffer.
On devices that support a single log file, the log file has a specific capacity. When the capacity is
reached, the system deletes the earliest messages and writes new messages into the log file. The directory
of the log file varies with the device models. Typically, the log file is saved in the directory
/logfile/logfile.log.
