Saving system information to the log file
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 save the log file manually.
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, which is usually set to 24 hours. You can also manually save the logs while the
device is not busy. After the logs in the log file buffer are saved into the log file, the system clears the log
file buffer.
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 is /logfile/logfile.log.
