    However, because the definition of fixed priority process in-loop monitoring has a higher priority, if the command is issued when monitoring has stopped by /hitachi/etc/swdt.conf (OFF is defined for the INLOOP symbol), the command terminates abnormally without restarting monitoring. If the command is issued when monitoring has already started, the command terminates normally without doing anything.

    By using Docker, you can deploy application programs, libraries, and prerequisite programs as containers in the operation environment (CE50-10). A container is provided as a single image file. By transferring an image file from the development environment to the operation environment, you can run the application program in the same environment as the development environment.

    Log files, which are stored in /var/log, are important for finding signs of security attacks or for investigating security accidents. There is a limit on the amount of log data that can be stored in CE50-10. Due to these specifications, log files are automatically deleted after a certain period has passed after the log data is generated.
