Collecting log information

Log information records daily information, user actions, system failures, system safety, and system
debugging. It includes diagnosis monitoring log messages, diagnostic log messages, system log
messages, and debug log messages.
To obtain the most recent log information, save the collected log messages to a log file.
To collect log information:
1. The system automatically saves diagnosis monitoring log messages to a log file.
By default, diagnosis monitoring log files are saved in the drvmon folder under the root
directory of the storage device.
2. The system automatically saves maintenance information to a file.
By default, maintenance information is saved in the info folder under the root directory of the
storage device.
3. Save diagnostic log messages from the log buffer to a log file.
