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 log file buffer before they are saved into a log file. The system writes the logs in

the log file 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

log file buffer are saved into the log file successfully, the system clears the log file buffer.

A log file has capacity limitations. When the size of a log file reaches the maximum value:

If the device only supports a single log file, the system will delete the earliest message(s)and write new

message(s) into the log file. The directory of a log file varies with the device models. Typically, a log file

is saved in the directory /logfile/logfile.log.
